IMPORTANT SAFETY INFORMATION
Springs, cables, and bottom fixtures are under extreme spring tension. NEVER ATTEMPT TO REMOVE
FASTENERS ON THESE COMPONENTS UNLESS THE SPRINGS ARE COMPLETELY UNWOUND.
NOTE - All fasteners that are colored in RED are under extreme tension and must never be removed unless
the springs are unwound and all spring tension is released.
CAUTION - Due to the extreme spring tension, never wind or unwind without the proper winding bars. Cold
rolled steel bars 18” to 22” that properly fit the winding cone holes are recommended.
Keep hands and fingers clear of section joints, track, and other door parts when operating the door. The lift
handle, step plate, and pull rope are provided for the safe operation of the door.
CAUTION- ACQ GREEN TREATED LUMBER will corrode zinc and galvanized coated fasteners and
components. Use fasteners appropriate for ACQ lumber. Protect door components as required.
Do not permit children to play underneath or with any garage door operating controls.
Always have the door in view to ensure its travel is free and clear before operating the electric garage door
opener.

BEFORE YOU BEGIN: PLEASE READ THIS
• Take heed of the NOTES and CAUTIONS in this book. They will save you from having to
redo your work.
• Study the installation instructions and illustrations before you begin work to understand what
the various components are and the sequence of assembly.
• Note that the RED FASTENERS are used on all components that are under spring tension.
This serves as a WARNING that serious harm could occur if the fastener is removed while
under spring tension.
• Verify your type of door and track so you can refer to the proper illustrations and sections of
this manual.
• It is recommended to pre drill 1/4” holes for ALL 5/16” x 1 3/4” wood lags...ESPECIALLY
THE CENTER BEARING PLATE that attaches the spring(s) to the wall. This prevents the
wood from splitting out and gives the most secure attachment.
• Remove the PROTECTIVE FILM from the sections upon installation. If the film is allowed to
get wet the adhesive may transfer from the film to the section.
• If only one section has a CENTER STILE use it for the top section. It’s for draw bar operator
attachment.

Commercial Steel Garage Door - OWNERS MANUAL
STEP 1:
PREPARE OPENING
Check that the opening is ready. For wood jambs
check that the rough opening equals the door
size. The jamb should be a substantial high quality
2x6 type material. For steel jambs the door will
be 2” wider than the opening. The door will seal
on the vertical track angle mount. Check that you
have the required headroom, side room, and back
room (Fig. 1). The jambs need to be plumb and
the header level to have a square opening. The
vertical jambs and the “header jamb” should be
flush with each other. The inside surfaces of the
jambs where the door will mount should be free of
any protruding objects (nails, bolts, screws) that
may interfere with the door.
STEP 2:
Figure 1
CAUTION!
NEVER INSTALL DOOR COMPONENTS
DIRECTLY ON A SOFT SURFACE LIKE
SHEETROCK OR BUFFALO BOARD!
WEATHER STRIP
WOOD JAMBS: Tack the Vinyl Door Stop in place
with the flat edge placed 1/8” from the inside edge
of the door jambs and header (Fig 2). Six or seven
penny galvanized nails work well.
NOTE:
• IF YOU WILL BE USING ANGLE MOUNT
WEATHER STRIP OR ALUMINUM VINYL
PERIMETER SEAL FOR STEEL JAMBS, THESE
WILL BE APPLIED LATER.
• DOOR STOP IS AN OPTION WHICH MUST
BE ORDERED IN ADDITION TO THE DOOR
PACKAGE.
Figure 2
STEP 3:
ORGANIZE
Set your sawhorses up in a clear convenient area.
Be sure there is nothing on the sawhorses that will
dent or mar the paint of the sections. Spread the
hardware out on the floor near the sawhorses.
Organize it into groups so you can easily find the
parts as you go. Organize the fasteners in the
hardware box in the same manner.
Page 5
Commercial Steel Garage Door - OWNERS MANUAL
Figure 3
STEP 4:
BOTTOM SECTION
ATTACHING PARTS:
Lay bottom section across sawhorses.
NOTE: FOR LOW HEADROOM APPLICATIONS
REFER TO PAGE 26. FOR ALL OTHER
APPLICATIONS USE THE FOLLOWING
INSTRUCTIONS.
BOTTOM FIXTURES: (Fig. 3). If the left and
right bottom fixtures are attached together, bend
them back and forth at the joining tabs until they
separate. Attach cable to right and left hand bottom
fixtures with 1/4” clevis pin and cotter key. Position
bottom fixtures along bottom edge of end stiles
and fasten with 5/16” x 5/8” RED HEAD parkers,
leaving the bottom holes open for installation of
Page 6
roller carrier. Place the bottom fixture roller carriers
in position and fasten with 5/16” x 5/8” RED HEAD
parkers in the upper holes. Use RED HEAD self
tappers in the lower holes (Fig. 3).
END HINGES: Refer to (Fig. 4) to determine the
proper number hinge to start with. Position the
hinge over the pre-punched holes on the end stile
at the top of the section. Orient hinges as shown in
(Fig. 5). Fasten hinges with 1/4” x 3/4” self tappers.
INTERMEDIATE HINGES: Position a #1 hinge over
the pre-punched holes at the top of the section on
each intermediate stile. ThermoGuard models use
Tog-L-Lock marks to determine hinge position.
(SEE FIGURE 5 FOR PROPER ORIENTATION
OF HINGES.) Fasten hinges with 1/4” x 3/4” self
tappers.
Commercial Steel Garage Door - OWNERS MANUAL
STEP 5:
BOTTOM SECTION
STEP PLATE:
Follow the appropriate
instructions below depending
on your type of lock:
Figure 5
KEYED LOCK- Two step plates are provided in
the hardware box. One is for the inside and one for
the outside of the door. The carriage bolts and tube
spacers are located in the keyed lock package. The
step plates should be attached to the stile directly
under the lock and positioned at the bottom edge of
the bottom section.
Using the step plate as a template, drill two 7/16”
holes using care to drill straight and true. The other
end of the hole you drill will locate the step plate on
Figure 4
the outside of the door. Insert the spacers. Fasten
step plates to inside and outside of section using the
two 1/4” carriage bolts and kep nuts provided.
Figure 6
Page 7
Commercial Steel Garage Door - OWNERS MANUAL
CAUTION:
DO NOT OVERTIGHTEN BOLTS
ON STEP PLATE
INSIDE SLIDE LOCK- You received one step
plate for the inside of your door. Location of
the step plate varies according to preference.
Generally it is put on the end of the door
nearest the walk-in access, either on the first
stile in from the end of the door or on the
bottom fixture directly above bottom roller.
Attach using 1/4” x 7/8” self tappers (Fig. 6).
STEP 6:
PULL ROPE
Install pull rope only if door will be hand
operated. DO NOT INSTALL THE PULL
ROPE IF THE DOOR WILL BE OPERATED
BY AN ELECTRIC OPENER. Tie a knot in
each end of rope. Drill a 1/4” hole in the bottom
fixture as close to the bottom roller as possible
making sure to leave room for the rope clip.
Fasten rope to bottom fixture using rope clip
and 5/16” x 5/8” RED HEAD parker (Fig. 3).
Let opposite end of rope hang loose.
STEP 7:
STRUTS
Use the charts on the next page to determine
what sections to put the struts and trusses on
for your door. These charts give the typical
locations for 2” Steel Doors and the 3” Energy
Saver doors.
NOTE: IF YOU HAVE A CU 175 REFER TO
THE SEPARATE INSTRUCTION SHEET FOR
STRUT ATTACHMENT.
GENERAL GUIDELINES:
Top sections need the most support. If you
have a combination of trusses and struts a
truss will always go on the top section. If you
have a combination of 3” and 2” struts the 3”
strut will always go on the top section. If there
is only one strut for the door locate it on the
top section.
Page 8
STRUT LOCATION ON THE SECTIONS
On BOTTOM and INTERMEDIATE SECTIONS:
For all C2ES,
C3ES, Ribbed, and
THERMO
ThermoGuard models,
GUARD
MODELS
place the struts and
trusses in center of the
section (For window
sections, place strut
above the window and
below the hinges) (Fig.
7a).
For all Thermal Steel
models (Fig. 7), strut
attachment points must
be in the area of the
hidden hinge plates.
Figure 7a
THERMO
STEEL
MODELS
On TOP SECTIONS:
For all door models,
place the strut at the
very top of the section,
above the top fixtures.
Figure 7
The exception to this
would be a door with LHR track (Fig. 45). If a truss is
required, place the truss in center of the section, below
where the operator arm would attach.
INSTALL THE STRUT: To install a strut on a section,
place the section on saw horses and place the strut in
position on the section. Adjust the sawhorses in or out
so the section sags 1/2” or so under the strut (Fig. 8
& 9). First, fasten strut to end stiles on both ends with
1/4” x 7/8” self tappers. Then fasten strut to center stile
with 1/4” x 7/8” self tappers. Finally, fasten strut to any
remaining intermediate stiles.
NOTE: PREPUNCHED HOLES IN STRUTS DO NOT
ALWAYS ALIGN WITH THE STILES.

STEP 8:
BOTTOM SECTION
REMOVE THE PROTECTIVE FILM FROM
THE OUTSIDE FACE OF THE SECTION. To
aid removal use a knife to LIGHTLY scribe a
line where the film runs under the end stiles
and the aluminum bottom astragal retainer.
Install the hinges, rollers, and bottom fixtures (Fig
10).
Figure 8
NOTE: IF YOU HAVE TWO ROLLERS THAT
ARE LONGER THAN ALL THE REST THEY
WILL GO IN THE BOTTOM FIXTURES.
STEP 9:
INSTALL THE BOTTOM SECTION
AND VERTICAL TRACK
Determine your type of track and jamb and follow
the appropriate instructions below:
PREP THE ANGLE MOUNT VERTICALS: Loosen
the 1/4” track bolts that fasten the track to the
angle mount (or jamb brackets) so the track can
be adjusted in and out. If using ANGLE MOUNT
WEATHERSTRIP, clip it on the 3” leg of the angle
mount at this time (Fig. 11).
Figure 9
Figure 10
Page 10
Figure 11
Commercial Steel Garage Door - OWNERS MANUAL
PREP THE JAMB BRACKET MOUNT
VERTICALS: Assemble the jamb brackets to the
vertical tracks, matching the lowest numbered
jamb bracket with lowest ADJUSTABLE SLOT.
Match the remaining jamb brackets in ascending
order with additional ADJUSTABLE SLOTS (Fig.
12). Attach the jamb brackets to vertical tracks
with 1/4” x 5/8” carriage bolts and 1/4” kep nuts.
FINGER TIGHTEN ONLY.
ALL DOORS:
Position the bottom section inside the opening
against the jambs. The bottom section must
be leveled by temporarily shimming up the low
side. Use a 2’ or 4’ level. Center the section in the
opening (Fig. 13).
Figure 12
Hook vertical track over the rollers on the end of
the bottom section and swing it into place against
the jamb (Fig. 14). Position bottom of track 1/2”
or so above floor (It works well to set the track on
a block of wood to hold it at the proper height.).
Raising the tracks allows adjustment in and out
and will reduce corrosion. Position vertical track so
that the tops of both sides are level with the other.
Since the bottom section is level, you may level
the top of the vertical track by measuring from the
top of the vertical track to the top of the bottom
section and setting both vertical tracks at the same
distance.
Also, the two vertical tracks will be installed in
a “wedge” shape compared to the door. For 2”
TRACK, space the bottoms of the tracks 3/8” from
the door and space the tops of the tracks 5/8” from
the door.
Figure 13
Figure 14
Page 11
Commercial Steel Garage Door - OWNERS MANUAL
This has the effect of centering the door every time
it goes up and down. If you are using 3” TRACK
this spacing should be 1/2” and 7/8” respectively
(Fig. 15).
Fasten the angle mount (or jamb brackets) to the
jamb with the appropriate fasteners. For STEEL
JAMBS use 5/16” X 1” self tappers (Fig. 11). For
WOOD JAMBS (Fig. 14 shows a final assembly),
make a 1/4” pilot hole and use 5/16” x 1 3/4” wood
lags.
NOTE: Enough fasteners are provided
to anchor the angle mount to the jamb
approximately every 2’. Start at the lower most
hole and work up from there. There may be
holes that are unused.
STEP 10:
SECTION PLACEMENT
Figure 15
If your new door has a combination of 18” and 21”
or 21” and 24” sections, you must decide which
sections will be placed where in the door. If your
door has only one larger section, the factory will
make it into a bottom section. If there are two
larger sections, one will be the bottom and the
other should be the top. After this, as a general
rule ,place the larger sections toward the bottom
and the smaller sections toward the top.
NOTE: LEAVE THE HINGE / ROLLER OFF
THE RIGHT SIDE. THEY WILL BE INSTALLED
AFTER THE SECTION IS STACKED IN THE
OPENING.
NOTE: If there is a “TOP SECTION” with a
center stile (for a drawbar operator), ensure
that it is used at the top of the door.
STACK SECOND SECTION
STEP 11:
SECOND SECTION PREP
Remove the film from the section. Position the
proper hinges at the top of the section in the same
manner as with the bottom section. Use the next
size larger hinges on the end stiles and #1 hinges
on the intermediate stiles as required (Fig. 4).
Fasten hinges with 1/4” x 3/4” self tappers.
Page 12
Install the strut as required. If a keyed lock is
utilized install it in the second section using the
instructions in the commercial keyed lock package.
STEP 12:
Stack the second section in the opening. Hook the
roller on the left side of the section into the track
and swing the section into the opening (Fig. 16).
Install the right hand hinge/roller assembly.
NOTE: If desired you can leave all the end
hinges off, stack the section in the opening
and then install both sets of end hinges with
rollers.
Fig. 17 shows a method of clamping the section
in place with a vise grip until the end hinges are
installed. Fasten hinges from the bottom section
to the second section using the 1/4” x 3/4” self
tappers.
Commercial Steel Garage Door - OWNERS MANUAL
Figure 16
Figure 17
STEP 13:
REMAINING SECTIONS
Add appropriate hardware and install the remaining
sections. If there is a window section ensure
it will go in the proper place. REMOVE THE
PROTECTIVE FILM FROM ALL SECTIONS
STEP 14:
TOP SECTION PREP
FOR LOW HEADROOM APPLICATIONS REFER
TO PAGES 26-29
If a strut is required, place the strut at the very top
of the section and fasten according to instructions
in step 7 (Fig. 18). Position the top fixture directly
below the strut with the adjusting bolts facing up.
Attach to the section with 1/4” x 7/8” self tappers.
Loosen the two 5/16” nuts on each top fixture
so that the roller carrier can slide in and out for
later adjustment. IF YOUR DOOR HAS NO TOP
STRUT, PLACE THE TOP FIXTURES 2 1/2”
BELOW THE TOP OF THE SECTION.
STACKING THE TOP SECTION: You can either:
1) Stack the top section now and hold it in place
with nails, clamps, C clamps, or vise grips, as
required or 2) Wait to stack the top section until the
horizontal tracks are installed.
Figure 18
NOTE: IF AN ELECTRIC DRAWBAR OPENER
IS TO BE ATTACHED TO THIS DOOR, THE
TOP SECTION MUST BE REINFORCED WITH A
STRUT AND THE OPERATOR ARM MUST BE
ATTACHED SO THAT IT IS APPROXIMATELY
IN LINE WITH THE TOP ROLLERS. IF THESE
INSTRUCTIONS ARE NOT FOLLOWED THE
WARRANTY WILL BE INVALID.
Page 13
Commercial Steel Garage Door - OWNERS MANUAL
STEP 15:
SET VERTICAL TRACK
Snug the top of the vertical track toward the jamb
against the highest roller. Tighten the track bolts in
the flag bracket/angle mount to hold it in position.
This enables you to properly locate the horizontal
track for the next step. Do not tighten the other
track bolts on the vertical at this time. That will be
done later.
STEP 16:
INSTALL TOP TRACKS
It is now time to install the top tracks. Turn to the
appropriate section for your application within step
16 and follow the instructions there.
STANDARD RADIUS
(Fig. 6 shows a typical installation.)
HORIZONTAL TRACK:
Suspend the rear of the horizontal track assembly
from the ceiling with rope (Fig. 19). Position the
front of the horizontal track on top of the vertical
track and attach using the 1/4” x 5/8” track bolts
and 1/4 keps nuts and the 3/8” x 3/4” carriage bolt
and RED flange nut (Fig. 20).
Figure 19
Only finger tighten the bolts at this time.
Check that the horizontal track is level or slightly
up. With the horizontal and vertical tracks properly
aligned (so the rollers will roll through the joint
smoothly), tighten the bolts to secure the horizontal
track in place.
TOP FIXTURE: Slide adjustable bracket on top
fixtures (Fig. 20) away from door until the top
section is tight against the door-stop and tighten
the adjusting bolts.
END BEARING PLATE: Attach the End Bearing
Plates as shown in (Fig. 20). Use the 3/8” x 3/4”
carriage bolts and RED flange nuts and RED
HEAD parkers or RED HEAD wood lags as
required.
Now go to step 17.
Page 14
Figure 20
Commercial Steel Garage Door - OWNERS MANUAL
Figure 21
HIGH LIFT
(Fig. 21 shows typical installation.)
HORIZONTAL TRACK:
Locate the left hand “HIGH LIFT VERTICAL
TRACK”. Attach it to the top of the verticals with
two 1/4” x 5/8” track bolts and 1/4” keps nuts (Fig.
22). Attach the left hand HORIZONTAL TRACK
with the head plate to the top of the high lift vertical
track just installed, with two 1/4” x 5/8” track bolts
and 1/4” keps nuts. Use a level to plumb it in place
so the HIGH LIFT VERTICAL TRACK is exactly
vertical. Secure the head plate to the jamb with
appropriate RED HEAD fasteners (Fig. 23).
Ensure there is a good fit between all the track
joints so the rollers can pass smoothly.
TOP FIXTURE: Slide adjustable bracket on top
fixtures (Fig. 22) away from door until the top
section is tight against the door stop and tighten the
adjusting bolts.
The back hang and spring bumpers will be installed
later. Now go to step 17.
Use a temporary rope if/as required to support the
rear of the horizontal tracks during this process.
Install the right hand track in the same manner.
Instead of using a level to plumb the right hand
track, measure the distance between the vertical
tracks at the top of the door. Then locate the right
hand head plate to achieve the same distance
between the upper tracks. Fig. 24 shows how
to measure this as “Distance 1” and “Distance
2”. Anchor the right hand head plate with the
appropriate RED HEAD fasteners.
Figure 22
Page 15
Commercial Steel Garage Door - OWNERS MANUAL
Figure 23
FULL VERTICAL
(Fig. 24 shows a typical installation.)
Attach the left hand UPPER VERTICAL LIFT
TRACK to the top of the verticals with two 1/4” x
5/8” track bolts and 1/4” keps nuts (Fig. 22). Use a
level to plumb it in place so the Upper Vertical Lift
Track is exactly vertical. Secure the head plate to
the jamb with appropriate RED HEAD fasteners
(Fig. 25).
Install the right hand upper vertical lift track in the
same manner. Instead of using a level to plumb the
right hand track, measure the distance between the
vertical tracks at the top of the door. Then locate
the right hand head plate to achieve the same
distance between the upper tracks. This is shown
as Distance 1 and Distance 2 on Fig. 24. Anchor
the right hand head plate with the appropriate RED
HEAD fasteners.
Ensure there is a good fit between the lower
and upper verticals so that the rollers can pass
smoothly through the joints.
TOP FIXTURE: Slide adjustable bracket on top
fixtures (Fig. 22) away from door, until the top
section is tight against the door-stop, and tighten
the adjusting bolts.
Page 16
Figure 24
Figure 25
The SPRING BUMPERS and SWAY BRACES will
be installed later. Now go to step 17.
ROOF PITCH
(Fig. 26 shows typical installation.)
HORIZONTAL TRACK: The horizontal track will
follow the incline of the roof. Suspend the rear of
the horizontal track assembly from the ceiling with
rope (Fig. 19).
Commercial Steel Garage Door - OWNERS MANUAL
Figure 26
Position the front of the horizontal track on top of
the vertical track and attach using the 1/4” x 5/8”
track bolts and flange nuts and the 3/8” x 3/4”
carriage bolt and RED flange nut. Only finger
tighten the bolts at this time. Ensure the rear of the
tracks are at or slightly above their final position.
Ensure the horizontal tracks line up properly over
the vertical tracks (so the rollers will roll through
the joint smoothly). Tighten the bolts to secure the
horizontal track in place.
Use the 3/8” x 3/4” carriage bolts and RED flange
nuts and RED HEAD Parkers or RED HEAD
wood lags as required to anchor the bearing plates
in position.
Now go to step 17.
NOTE: The factory has cut all angles based on
the pitch specified. Actual field conditions may
vary and require small modifications to the joint
between the vertical and horizontal tracks.
TOP FIXTURE: Slide adjustable bracket on top
fixtures (Fig. 27 ) away from door until the top
section is tight against the door-stop and tighten
the adjusting bolts.
END BEARING PLATE: Attach the End Bearing
Plates (Fig. 27). The EXTENSION PLATE is used
to raise the shaft line high enough so the top
section will clear the drum. As a general rule the
steeper the incline on the track, the higher you
need to raise the end bearing plate.
Figure 27
Page 17
Commercial Steel Garage Door - OWNERS MANUAL
LOW HEADROOM FRONT/REAR:
Installation is the same as “Standard Radius”
except the End Bearing Plates are factory installed
on the horizontal track. Install the top section if not
done previously. Install the LHR top fixtures. Put
1/4” x 7/8” self tappers in the slots only, so they can
be adjusted to final position later (Fig. 28).
STEP 17:
INSTALL CENTER BEARING PLATE(S)
Refer to the Spring Assemblies Illustration (Fig.
29) and determine which spring/shaft configuration
your door uses. Arrange the Center Bearing
Plate(s) along the shaft line so there is enough
room for each spring.
REMEMBER- A SPRING MAY STRETCH A
COUPLE INCHES AS IT IS WOUND!
Figure 28
NOTE: For CENTER PULL and COUPLED DUAL
SHAFT LINE doors refer to the instruction
insert located in the hardware box.
The Center Bearing Plate(s) must be in line with
End Bearing Plates so the shaft line is straight.
This may be accomplished by measuring from the
top of the door to the center of the shaft line at
the End Bearing Plates. Use that measurement to
locate the Center Bearing Plate above the door.
Figure 30 shows a typical installation.
FOR WOOD HEADER: Attach Center Bearing
Plate(s) to the header using three 5/16” x 1 3/4”
RED HEAD wood lags. Pre-drill holes with 1/4” bit
to prevent wood from splitting.
FOR STEEL HEADER: Fasten with three 5/16”
x 5/8” RED HEAD parkers per Center Bearing
Plate. Pre drill a 1/4” pilot hole as required.
Page 18
Figure 29
-CAUTION -
The Center Bearing Plate(s) anchors the
springs and must be fastened securely to the
wall. NEVER MOUNT ON A SOFT SURFACE
SUCH AS SHEET ROCK. NEVER ATTEMPT TO
REMOVE THE CENTER BEARING PLATE IF
THE SPRINGS ARE WOUND.

STEP 18:
SPRING SHAFT ASSEMBLY
NOTE: FOR LOW HEADROOM APPLICATIONS
REFER TO PAGE 26. FOR ALL OTHER
APPLICATIONS, USE THE FOLLOWING
INSTRUCTIONS.
Refer to the Spring Assemblies Illustration (Fig. 29)
and determine which spring/shaft configuration your
door uses. Assemble the components accordingly.
Place the spring shaft on saw horses. Insert a
BEARING into one spring anchor cone (Fig. 31a)
and slide the spring(s) on the shaft(s) (It is easier to
work with heavier spring assemblies on the floor.).
NOTE: FOR TUBE SHAFT, ONLY ONE CENTER
BEARING IS REQUIRED WHETHER THE DOOR
IS SUPPLIED WITH ONE SPRING OR TWO.
FOR SOLID SHAFT, EACH SPRING WILL GET A
BEARING.
CAUTION: The springs are LEFT and RIGHT hand
wound. WHEN INSIDE THE BUILDING LOOKING
OUT the spring with the RED winding cone is on
the LEFT side of the door and the spring with the
BLACK winding cone is to the RIGHT side of the
door. Slide the cable drums on the shaft. The RED
drum goes and the LEFT side and the BLACK
drum on the RIGHT side. Ensure the set screws are
facing “IN” toward the center of the door.
SHAFT COUPLER: If your door utilizes a split solid
shaft, install the SHAFT COUPLER by removing
the 3/8” x 2” joining bolts and installing a coupler
half on each of the shafts. Insert the square
keyways and tighten the setscrews and lock nuts
(Figs. 31a & 32). Save the joining bolts for after the
springs are wound.
NOTE: If a JACKSHAFT OPERATOR is going to
be used, one shaft will be longer than the other.
USE THE LONGER SHAFT ON THE SIDE THE
JACKSHAFT OPERATOR WILL BE INSTALLED.
NOTE: If your door utilizes “PILLOW BLOCK
BEARINGS” on your End Bearing Plates, you
must use a SPACER between the drum and the
End Bearing Plate (Fig. 33).

STEP 19:
INSTALL SPRING ASSEMBLY
Use the appropriate instruction below:
TUBE SHAFT: Lift the spring assembly up into
position. Slide the left end of Shaft through the left
End Bearing Plate and slide back through right End
Bearing Plate (It may be helpful to slightly tighten
Page 20
Figure 33
the spring set screws on the Shaft to prevent the
springs from moving during this process.).
SPRINGS WITH RED CONES MUST BE FACING
THE LEFT SIDE OF THE DOOR AND SPRINGS
WITH BLACK CONES MUST BE FACING THE
RIGHT SIDE OF THE DOOR.
Commercial Steel Garage Door - OWNERS MANUAL
Figure 34
Fasten to Center Bearing Plate with 3/8” x 1 1/2”
bolts and the RED 3/8” flange nuts and tighten (Fig.
34). Be sure the shaft line is straight both up and
down and in and out from the wall.
SOLID SHAFT: Lift the left spring assembly up
into position and slide the shaft through the End
Bearing Plate. Fasten the anchor cones to Center
Bearing Plate with 3/8” x 1 1/2” bolts and the RED
3/8” flange nuts and tighten (Fig. 31). Be sure the
shaft line is straight both up and down and in and
out from the wall. Repeat process for the right
spring assembly. Butt the left and right shaft coupler
halves against each other, but do not install the 3/8”
x 2” joining bolts yet.
NOTE: THE SPRING ANCHOR CONES MUST FIT
SNUGLY AND EVENLY AGAINST THE CENTER
BEARING PLATE.
STEP 20:
SET THE CABLE DRUMS
Center the shaft line so there is an equal amount
extending through the left and right End Bearing
Plates.
NOTE: If your application will have a Jackshaft
Operator, you will have solid shafts. One of the
shafts will be 12” longer for the operator to
hook up to.
Figure 35
Use the appropriate instruction below:
NOTE: On FULL VERTICAL and HIGH LIFT you
will have “extra” cable length. Do not cut the
cables. Wrap the extra cable on the drum.
TUBE SHAFT: Position the left (RED) cable drum
tightly against the left End Bearing Plate and tighten
the set screws. Bring cable up between wall and
roller stem, behind the cable drum and position the
cable bead into the notch on the outside edge of
cable drum (Fig. 35). ROTATE THE CABLE DRUM
AND THE SHAFT UNTIL CABLE IS TIGHT. Check
to be certain there is no “loose” cable on the drum
and that the cable runs free and clear all the way
to the bottom fixture. Clamp a vise grip on top of
the shaft and against the header to maintain cable
tension (Fig. 36). Take note of the cable tension you
have. You will want to duplicate that tension on the
right side.
NOTE: DO NOT SEVERELY OVERTIGHTEN SET
SCREWS ON DRUMS OR SPRINGS. This would
distort and weaken the shaft.
Position the right (BLACK) cable drum tightly
against the right End Bearing Plate and bring cable
up as before and fasten to cable drum. Rotate the
cable drum until this cable has the same tension as
the left cable. Tighten the set screws in sequence
(Fig. 37).
Page 21
Commercial Steel Garage Door - OWNERS MANUAL
Figure 36
NOTE: CABLE TENSION ON EACH SIDE
MUST BE EQUAL SO THE DOOR WILL BE
LEVEL AND OPERATE PROPERLY.
SOLID SHAFT: Make sure the left and right shaft
couplers are butted up against each other. Starting
on the left side, slide the cable drum against the
End Bearing Plate. Insert the Square Key in the
keyway and tighten the setscrews (Fig. 31b).
Bring cable up between wall and roller stem,
behind the cable drum, and position the cable
bead into the notch on the outside edge of cable
drum (Fig. 35). ROTATE THE CABLE DRUM AND
THE SHAFT UNTIL CABLE IS TIGHT. Check to
be certain the cable bead is seated against the
cable drum and that there is no “loose” cable on
the drum. The cable must run free and clear all
the way down to the bottom fixture. Clamp a vise
grip on top of the shaft and against the header
to maintain cable tension (Fig. 36). Repeat this
process on the right side.
Page 22
Figure 37
Commercial Steel Garage Door - OWNERS MANUAL
STEP 21:
WINDING SPRINGS
Clamp the door down.
- CAUTION -
CLAMP DOOR SECURELY CLOSED ON BOTH
SIDES USING C-CLAMP VISE GRIPS BEFORE
WINDING ANY TENSION ONTO SPRINGS.
SPRING TENSION IS DANGEROUS. ONLY USE
PROPER SIZED WINDING BARS. NEVER USE
SCREWDRIVERS OR OTHER TOOLS TO WIND
SPRINGS.
COMMERCIAL DOOR SPRINGS CAN BE
LARGE AND POWERFUL. MAKE SURE
LADDERS, SCAFFOLDING OR LIFTS ARE
SECURE AND STABLE AND PROVIDE A
GOOD POSITION FROM WHICH TO WIND THE
SPRINGS.
Make a line across the spring(s) to assist in
counting turns as you wind the spring. A grease
pencil, chalk, or spray paint works well (Fig. 36).
Using two cold rolled steel winding bars that fit
snugly in the holes of the winding cone, wind
springs the number of turns (COMPLETE
REVOLUTIONS) specified on the spring tag. The
bars should be at least 18” long. The bigger the
springs, the longer the bar should be.
AS A DOUBLE CHECK: ALWAYS WIND IN THE
DIRECTION INDICATED BY THE CUT OFF END
OF THE SPRING WIRE (Fig. 38).
Wind springs carefully, keeping hands as far away
from springs as possible for best leverage (Fig.
36). The spring will stretch as you wind it. Upon
completing the number of turns specified, be sure
the spring has stretched enough and is not “bound
up”. Tighten set screws on spring winding cone
while maintaining spring tension (If you have a
SOLID SHAFT, one of the set screws is typically
run in the 1/4” keyway of the shaft.). After winding
all springs, go to Step 22.
LEAVE THE WARNING TAG ATTACHED
TO THE SPRING!
IF YOU MUST REDUCE SPRING TENSION OR
UNWIND COMPLETELY: Follow all precautions
for winding springs. If there is only one spring on
the door, clamp a vise grip on the spring shaft to
hold the cable drums in place (Step 20). Insert
winding bar in the spring cone and hold tension
against the spring. Carefully loosen the set screws
and hold the full spring tension. Unwind the spring
the desired amount. Reset set screws as required.
Figure 38
Page 23
Commercial Steel Garage Door - OWNERS MANUAL
STEP 22:
SHAFT COUPLER:
(SOLID SHAFT ONLY) Install and tighten the three
3/8” x 2” joining bolts (Fig. 32).
STEP 23:
BACK HANG: ALL DOORS EXCEPT
FULL VERTICAL
Use the following to determine your doors back
hang requirements:
STANDARD RADIUS OR LOW HEAD ROOM:
• Doors up to 8’ high - One back hang per side.
• Doors over 8’ high and up to 14’ high - Two
back hangs per side.
• Doors over 20’ wide OR over 14’ high - Three
back hangs per side.
HI LIFT:
• Back of horizontals up to 8’ from header - One
back hang per side.
• Back of horizontals 8’ to 16’ from header - Two
back hangs per side.
• All Doors over 20’ wide - One back hang per
side for every 6’ horizontal track.
Remove the vise grip(s) from the shaft line. While
keeping a good hold on the door (in case the
springs are overwound), remove the clamps holding
the door down. Raise the door approximately half
way up or to the first back hang position and clamp
in place. Ensure that the tracks are level or slightly
up and run parallel with the door with approximately
1/2” clearance between the track and the door.
Back hang the door (See your door types main
illustration for back hang examples.).
NOTE: PUNCHED ANGLE IS AN OPTION FOR
BACK HANG WHICH MUST BE ORDERED IN
ADDITION TO THE DOOR PACKAGE.
STEP 24:
FINAL ITEMS AND ADJUSTMENTS
Choose the final instructions for your application.
Page 24
STANDARD RADIUS, ROOF PITCH, & LOW
HEAD ROOM: Install 3/8” x 1 1/2” bolts at the rear
end of the horizontal tracks. These prevent the top
section rollers from rolling out the back of the track.
FULL VERTICAL: Install a SWAY BRACE on each
upper vertical track to prevent them from spreading.
Raise the door to its desired full open position,
clamp in place, and install the SPRING BUMPERS
(Fig. 25).
HIGH LIFT: Raise the door to its desired full open
position, clamp in place, and install the SPRING
BUMPERS (Fig. 21).
LOW HEAD ROOM:
TOP FIXTURES: With the door fully closed, final
adjust the top fixtures so the top section fully
closes. Add an additional self tapper in each so
the top fixtures can’t move. If a strut is required
at the top of the section (for doors with a drawbar
operator), install the strut over the top of the top
fixtures (Fig. 28).
ALL DOORS:
Attach the LIFT HANDLE and the INSIDE SLIDE
LOCK to the second section with self tappers
(Fig. 6). The door should work smoothly and easily
throughout its range of operation. Adjust spring
tension in 1/4” turn increments as required. Ideally,
the door should be able to rest on the floor, stop
half way up, and pull down reasonably well, out of
the opening.
With door closed, push the lower portion of vertical
track towards jamb until door fits lightly against door
stop and tighten the 1/4” kep nuts on jamb brackets/
angle mount.
Ensure that the rollers run smoothly through the
joint of the vertical and horizontal tracks. Use your
hammer or vise grips to make small adjustments if
they are not lined up well.
Check that the door is square in the opening and
the tracks are properly aligned.
Commercial Steel Garage Door - OWNERS MANUAL
WEATHER STRIP:
VINYL WEATHERSTRIP-WOOD JAMB: With the
door closed, check that the door stop is positioned
satisfactorily against the door and nail securely.
PERIMETER SEAL/BRUSH: Install with owner
supplied fasteners (Fig. 39).
TOP SEAL: Install on the top of the top section
with owner supplied fasteners (Fig. 40).
Check that all bolts and screws are tight. If
