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.
C EDGE PROTECTION: When there
is a drop o, 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 sucient to
provide this protection.
D CLEARANCE: A ramp must have a
minimum clear width of 1m.
E D RETURNS: Rail ends need to be rounded
or return smoothly into a oor, wall or post.
F EXTENSIONS: Stairs: Handrails should extend the
width of one stair tread and then level out for 300mm
Ramps: Handrail should extend parallel to walking
surface 300mm past the top and bottom of the ramp.

B RAMP UPRIGHT: The $base ange
is for mounting to angled surfaces. The angle is
xed by tightening the set screws. The railings
are attached in the same manner as the Standard
Upright. The bottom rails are connected with $(
on mids and $( on ends.
C WALL MOUNT: The %%"is connected to the
wall or wood posts using 6mm screws or bolts.
The %%" is attached to the railing with No. 12
self-drilling screws or pop rivets.
D D RETURNS: D returns are constructed with %%"s and
. The %%"hs are connected vertically with a small piece of
tube. This assembly is then joined to the top and midrail with
%%"s.
E ADJUSTABLE ANGLES: In order to
accomplish angles with a smooth surface, use
the %%" and %%"s. These are frequently
used at the top and bottom of ramps and stairs.

A STANDARD UPRIGHT: The $( base
ange is for mounting to level surfaces. The
%%" connects the railing to the %%"
tting.
B RAMP UPRIGHT: The $ base ange is for
angled surfaces. The upright angle is xed by tightening
the set screws. The railings are attached in the same
manner as the Standard Upright. The bottom rails are
connected with $( on mids and $( on ends.
C WALL MOUNT: The %%" is connected to the
wall or wood posts using 6mm screws or bolts.
The %%" is attached to the railing with No. 12
self-drilling screws.
D POST RETURN DRETURN: The
D-return connects to the post using the %%"
and %%". The %%" receives the small
end of the %%". The %%" is then joined to
the %%" using a %%".
E ADJUSTABLE ANGLES: In order to
accomplish angles with a smooth surface, use
the %%" and two %%". These are frequently
used at the top and bottom of ramps and
stairs.
F WALL RETURN: The %%" wall return ange is
connected to the wall or wooden posts with 6mm
screws or bolts. It is then connected to the pipe
with a %%".

POST MOUNTED BOTTOM RAIL END: The bottom rail on a
at surface terminates into a railing post using a $(.
BOTTOM RAIL HANDRAIL END: Connect the bottom rail to the wall
with a $( wall ange.
BOTTOM RAIL VERTICAL CHANGE: The vertical change on
the bottom rail of a ramp is typically done using a $(
.
HANDRAIL RAILING END: Mount the $( to the wall. The handrail
or mid-rail tube is then connected to this tting using a %%".

When the set screw is tightened, the angle of the bottom rail
will be xed.
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.
