TREX ALUMINUM ADA COMPLIANT HANDRAIL
STAIR APPLICATION 
ADA Handrail Guidelines
1.  ADA handrails can be installed using various design 
applications such as those for stairs, ramps, and 
horizontal applications. Designs include options 
for straight and 90° wall returns, 90° corners, and 
adjustable angles. Choose which is best for your 
needs before installing. Refer to railing profi les 
(page 56) for a more detailed parts list.
2.   The handrail system top rail should be 34" 
(864 mm) to 38   " (965 mm) above the surface. 
However, verifying height requirements with local 
building code offi cials before installing is important 
as codes vary in different areas.*
3.   Maintain a minimum clearance of 1-1/2   " (38 mm) 
between the handrail and any obstructions above 
or behind the handrail.
4.   The end loop return at all landings must extend 
12 " (305 mm) past the end of the ramp or stair 
application.*
5.   The slope of the handrail for the ramp should not 
exceed  1 " (25 mm) rise over a 12   " (305 mm) run.
6.  The maximum recommended span between 
supports is 6' (1.83 m) on center. Thus 
placement of posts is critical when installation 
of railing is being considered.*
7.   Rails are designed to have a tight fit into other
connecting components. It is critical to line these 
up in the correct orientation BEFORE connecting 
parts together. If it is necessary to shift or move a 
component on a rail, wrap with a protective cloth 
to prevent scratching as you may need to use a 
wide-mouth wrench to correct this.
8.   At any straight location where internal 
connector is used, it is CRITICAL to locate 
these as close to a wall mount as possible. 
9.   If using metal posts, pre-drill all locations for 
bracket attachment. (ALWAYS use a drill bit 
slightly SMALLER in diameter than the screw 
being used for attachment.)
10.   All elbow components can be cut down to allow 
for tighter angles. Cut a maximum of 2" (51 mm)
on each side if this is required.

information in regards to handrail requirements.
