RAMP APPLICATION
ADA Handrail Guidelines
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.
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.
34" (864 mm) to 38" (965 mm)
* Refer to the American Disabilities Act for detailed information with regard to handrail requirements.
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.
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.
