RECOMENDED TOOLS
ALLEN KEY
A size 7 or 8 allen key required for tightening set
screws in the fittings
SAW TO CUT TUBE
• Chop Saw
• Band Saw
• Hack Saw
DRILL
• Hammer drill may be needed when drilling
into brick or concrete
NEEDED MATERIALS
SELF DRILLING SCREWS (NO. 12) OR
MULTI-GRIP POP RIVETS
For attaching handrail to brackets
MOUNTING HARDWARE FOR BASE
FLANGES
• 6mm For Wall Mounts
• 12mm For Base Flanges
RECOMENDATIONS:
• Lag Screws
• Tapcons
• Bolts
• Chemical Anchors
(please refer to a fixing supplier for advice on selection)
INSTALLATION TIPS
• Cut the tube at the job site.
• Use the type 62 base flange when fitting to concrete, avoiding installing close to the
edge and instead of core drillng to prevent rust to upright.
• Center uprights not to exceed 1.8m when loadings not exceeding 0.74 KN / m are
required.
• Uprights must be offset from corners and bends in the railing.

BASIC PRINCIPLES OF DDA

A) HANDRAIL: Handrail must be a
continuous smooth surface. Handrail must
be on both sides of ramp or stairs.
B) HANDRAIL HEIGHT: Handrail must be
900mm-1.1m in height.
D) CLEARANCE: A ramp must have a
minimum clear width of 1m.
E) D RETURNS: Rail ends need to be rounded F) EXTENSIONS: Stairs: Handrails should extend the
or return smoothly into a floor, wall or post. width of one stair tread and then level out for 300mm
For assistance visit: www.keesafety.co.uk or call 01384 632 188
C) EDGE PROTECTION: When there
is a drop off, ramps require a curb or
curb rail to prevent wheel chairs from
slipping out from under the railing. In
some cases a mid rail is sufficient to
provide this protection.
Ramps: Handrail should extend parallel to walking
surface 300mm past the top and bottom of the ramp.

A) STANDARD UPRIGHT: The 62-8 base
flange is for mounting to level surfaces.
The 518-7 connects to 10-848 and 10-840C
fitting.
B) RAMP UPRIGHT: The 67-8 base flange
is for mounting to angled surfaces. The angle is
fixed by tightening the set screws. The railings
are attached in the same manner as the Standard
Upright. The bottom rails are connected with
89-8 on mids and 86-8 on ends.
C) WALL MOUNT: The 570-7 is connected to the
wall or wood posts using 6mm screws or bolts.
The 570-7 is attached to the railing with No. 12
self-drilling screws or pop rivets.

D) D RETURNS: D returns are constructed with 520-7s and
514-7. The 520-7s are connected vertically with a small piece of
tube. This assembly is then joined to the top and midrail with
514-7s.
E) ADJUSTABLE ANGLES: In order to
accomplish angles with a smooth surface, use
the 554-7 and 514-7s. These are frequently
used at the top and bottom of ramps and stairs.

F) WALL RETURN: The 565-7 wall return flange is
connected to the wall and then connected to the
tube with a 514-7.

A) STANDARD UPRIGHT: The 62-8 base
flange is for mounting to level surfaces. The
518-7 connects the railing to the 10-840C
fitting.
B) RAMP UPRIGHT: The 67-8 base flange is for
angled surfaces. The upright angle is fixed by tightening
the set screws. The railings are attached in the same
manner as the Standard Upright. The bottom rails are
connected with 89-8 on mids and 86-8 on ends.
C) WALL MOUNT: The 570-7 is connected to the
wall or wood posts using 6mm screws or bolts.
The 570-7 is attached to the railing with No. 12

D) POST RETURN D-RETURN: The
D-return connects to the post using the 567-7
and 10-848. The 10-848 receives the small
end of the 567-7. The 567-7 is then joined to
the 520-7 using a 514-7.
E) ADJUSTABLE ANGLES: In order to
accomplish angles with a smooth surface, use
the 554-7 and two 514-7. These are frequently
used at the top and bottom of ramps and
stairs.

F) WALL RETURN: The 565-7 wall return flange is
connected to the wall or wooden posts with 6mm
screws or bolts. It is then connected to the pipe
with a 514-7.

BOTTOM RAIL HANDRAIL END: Connect the bottom rail to the wall
with a 61-8 wall flange.
BOTTOM RAIL VERTICAL CHANGE: The vertical change on
the bottom rail of a ramp is typically done using a BC53-8
or a 55-8.
10-8

POST MOUNTED RAMP BOTTOM RAIL END: The bottom
rail on a ramp terminates into a railing post using a 86-8.
When the set screw is tightened, the angle of the bottom rail
will be fixed.
POST MOUNTED BOTTOM RAIL END: The bottom rail on a
flat surface terminates into a railing post using a 10-8.

HANDRAIL RAILING END: Mount the 561-7 to the wall. The handrail
or mid-rail tube is then connected to this fitting using a 514-7.
HANDRAIL BRACKET ATTACHMENT: Brackets attach to the handrail
tube with two No. 12 self drilling screws or pop rivets. Use high
quality hardware for the best results.
