Functional stair handrails must provide a ‘Power Grip’ where the fingers wrap most of the way around the diameter. Research has demonstrated that a ‘Power Grip’ is five times stronger than the ‘Pinch Grip’ used on an ornate guardrail.
Functional stair handrails specifications :
- Have a round profile between 1½†and 2†in diameter to allow hands to wrap around fully and achieve a ‘Power Grip’
- Extend the length of the entire stairway with no break, to ensure the railing can be gripped at all times.
- The handrail must be continuous through all slope changes and curves, across landings, and around corners.
- Mount with brackets that do not impede the movement of the hand along the railing. L-shaped brackets are preferred over brackets that slope on a diagonal.
- Have a minimum of 1½†between the handrail and the wall
- Terminate with a 90-degree return to the wall to prevent clothing, bags or emergency fire hoses from becoming hooked on the end
- Be able to withstand at least 500 lbs. of force in any direction
