ADA RAILING
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 profile page 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 officials 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 with regard to handrail requirements.
SAFETY NOTES
» 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.
