ADA Handrail Guidelines
6. T he 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. R ails 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. A t 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. A ll 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.
