STEP 1: WALL OPENING
A. Check wall opening width and height and verify these measurements against size of door to be installed.
B. Verify that jambs are plumb.
C. Check floor and header for level.
D. Check for adequate side clearance at jambs and clearance above and at sides of header. Check vertical and horizontal head
room requirements. See Clearance charts figure 1 for minimum requirements.
E. Verify that the guide mounting surface on the jamb is flush.
F. Make sure all parts required for installation are with the door.
STEP 2: MOUNTING PLATES (OPTIONAL EXCEPT FOR STEEL JAMBS)
A. If door will install to steel jambs, mounting plates for the door brackets are required and may be welded
or bolted to the jambs.
B. Top of mounting plates should be located 10" above top of opening and be level with each other. Side of
mounting plates should be even with edge of opening. If opening width is off, adjust locations accordingly.
See figure 2.
C. If mounting plates are bolted to jambs, orient flats of attachment bolts in a vertical plane. See
figure 2. Do not use a flat washer between bolt and mounting plate.
NOTE: DOOR DRIVE OPERATION MAY BE INSTALLED ON EITHER END OF DOOR ASSEMBLY.
STEP 3: BRACKETS TO GUIDES
A. Attach door brackets to guides, locating top surface of bracket 2" below top of guide. Use 2 each 1/4-20 x 5/8"
carriage bolts, 1/4-20 serrated flange hex nuts and 1/4" flat washers per bracket for tensioner end and the
non-tensioner (drive) end for push-up operation. See figures 6 and 7.
B. For reduced hand chain drive end, install drive bracket with 2 each 1/4-20 x 2-1/2" carriage bolts, 1/4-20
serrated flange hex nuts and 1/4" flat washers. Insert 1 each 1-1/4" O.D. x 1-3/8" long spacer tube between
guide and bracket at each bolt location. See figure 8.
C. For electric operation drive end, install drive bracket with 2 each 1/4-20 x 2-1/2" carriage bolts, 1/4-20 serrated
flange hex nuts and 1/4" flat washers. Insert 2 each 1-1/4" O.D. x 3/4" long spacer tubes between guide and
bracket at each bolt location. See figure 9.
STEP 4: GUIDES AND BRACKETS TO JAMB
A. Attach brackets and guides to jambs using fasteners shown in table 1.
B. The guides should be mounted centered about the opening and spaced curtain width + 1" apart, measured from
back of guide to back of guide. See figure 3. Both guides must be plumb.
C. Once both guides have been correctly positioned, attach them to the jambs using the appropriate fastener at
each hole location. See table 1.
D. Check top surface of brackets to verify they are level with each other. If they are not, loosen the bracket-toguide attachment fasteners and slide bracket(s) vertically until level. Tighten bracket to guide fasteners.
E. Install 3 bracket-to-jamb attachment fasteners for each bracket. See table 1.
WARNING!
DOOR CAN FALL IF BOTH BRACKETS ARE NOT SECURELY FASTENED TO THE JAMBS. ALL FASTENERS ATTACHING BRACKETS TO
JAMBS MUST FIT SECURELY INTO A STRUCTURAL MEMBER OR SURFACE. IF DOOR FALLS, SERIOUS INJURY OR DEATH
AND/OR DAMAGE TO DOOR CAN RESULT.

will be tightened against the axle later.
C. Slide cast axle support bracket over axle. See figures 4 and 8.
STEP 8: ELECTRIC DRIVE END
A. Locate 3 each 1" O.D. x 1-7/8" long spacer tubes and 5-3/4" long x 2-1/8" offset struts between 48 tooth
#41 sprocket and drum. Attach sprocket with 3 each 3/8-16 x 3-1/2" grade 5 hex bolts and 3/8" lock
washers.
B. Slide stamped axle support over axle, with arrow pointing toward wall. See figures 4 and 9.
STEP 9: LIFTING DOOR ASSEMBLY
A. Orient door with bottom bar located at 12 o'clock position.
B. Lift door assembly using a forklift that has padded forks in order to prevent damage to curtain.
C. Position door on brackets with tensioner and axle support resting safely on top of bracket flange.
D. Door should be positioned as close as possible to the header and still be able to rotate and clear bottom bar.
E. Each end of door should be equal distance from the header and the curtain must be centered in the opening.

and 3/8" flat washer.
B. Position chain hoist assembly on door bracket next to cast axle support and attach to door bracket using
2 each 3/8-16 x 3/4" grade 5 hex bolts, 3/8" lock washers and 3/8" flat washers. The spur gear on the hoist
will engage with the external teeth of the cast ring gear on the end of the drum. See figure 8.
C. Connect cast axle support bracket to side of chain hoist using 3/8-16 x 3/4" hex bolt and 3/8" lock washer.
See figures 4 and 8.

STEP 13: ELECTRIC DRIVE END
A. Attach stamped axle support to door bracket using 2 each 3/8-16 x 3/4" grade 5 hex bolts, 3/8" lock
washers and 3/8" flat washers. See figures 4 and 9.
STEP 14: SETTING INITIAL SPRING TENSION
WARNING!
EXTREME SPRING TENSION CAN CAUSE SERIOUS INJURY OR DEATH. INSTALLATION, REPAIRS AND
ADJUSTMENTS MUST BE MADE BY A TRAINED ROLLING SERVICE DOOR SYSTEMS TECHNICIAN
USING PROPER TOOLS AND INSTRUCTIONS. DOOR MUST BE FULLY OPEN WHEN MAKING ADJUSTMENTS.
A. Rotate door 1-1/2 revolutions in the direction that would send the bottom bar down through the guides.
B. While firmly holding the door at the bottom bar, cut the tape and plastic wrap that holds the door in a coil.
Direct the bottom bar down into the guides, stopping just past the head stop area.
STEP 15: HEAD STOPS
A. Slide head stop from outside of each guide. See figures 6 through 9.
B. Secure each head stop to guide with a 3/8-16 x 1/2” hex bolt and a 3/8” lock washer.
STEP 16: SLIDE LOCK, STEP PLATE AND PULL ROPE
A. Lower bottom bar and install slide lock and step plate using 2 each 1/4-20 x 1" hex bolts, 5/16-18 hex nuts,
1/4" flat washers and 1/4-20 nylon insert hex nuts. Do this at both ends of bottom bar. See figure 5.
B. Transfer the 1/4-20 x 1/2" carriage bolts and 1/4-20 serrated flange hex nuts that were removed from both
ends of the bottom bar to the 2 holes at the center of the bottom bar and angle.
C. For push-up operation only, install rope in one of the holes at the center of the horizontal leg of the bottom
bar angle.
STEP 17: POSITION DOOR
A. Fully open door.
B. At both ends of the door, slightly loosen all 3/8-16 x 3/4" hex bolts that go through the door bracket and
connect to the tensioner, axle support and chain hoist.
C. Push door assembly as close as possible toward header and still be able to rotate freely. Each end of door
should be equal distance from the header and the curtain must be centered in the opening.
D. Tighten securely all 3/8-16 x 3/4" hex bolts that were loosened in step 17B.
E. Tighten all 3/8-16 square head setscrews in tensioner and axle support at both ends of door.
STEP 18: CHECK DOOR OPERATION
A. Lower and raise the door to test door operation and balance.
B. If door is easy to close, but hard to open, increase spring initial tension.
C. If door is hard to close, but easy to open, decrease spring initial tension.
WARNING!
DOOR MUST BE FULLY OPENED WHEN MAKING ADJUSTMENTS.
STEP 19: ADJUST SPRING TENSION (if required)
A. Loosen all 3/8-16 square head setscrews in tensioner and axle support at both ends of door.
B. At tensioner end, place pipe wrench around end of axle so that pulling down on the handle will rotate the axle to
increase spring tension.
C. To increase spring tension, pull down on pipe wrench. The tensioner will automatically grip the axle and hold
the new tension setting.
D. To decrease spring tension, momentarily pull down on pipe wrench and then lift the spring roll pin on the
tensioner's knurled wheel. Gently let up on pipe wrench, allowing the axle to rotate to reduce the tension.
While holding the new tension, release the tensioner's spring roll pin. The tensioner will now grip the axle
and hold the new tension setting.
E. Tighten all 3/8-16 square head setscrews in tensioner and axle support at both ends of door.
F. Remove pipe wrench and operate door.
G. Repeat steps 19A through 19F as necessary.
