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.
*Refer to the American Disabilities Act for detailed
information in regards to handrail requirements.

» When cutting metal, ALWAYS wear proper safety
eyewear (as well as any other proper safety wear).
» Remove all burrs from cut ends before installation.
» Use of a non-ferrous metal blade is recommended.
