Final answer:
Type II handrails with a diameter over 6¬Ω inches must have a graspable finger recess of at least 2¬Ω inches for safety and accessibility.
Step-by-step explanation:
When designing Type II handrails that are greater than 6½ inches, the graspable finger recess must be not less than 2½ inches according to standard building codes and accessibility guidelines. According to building regulations, Type II handrails greater than 6¼" should have a graspable finger recess not less than 2¾". This means that the distance between the wall and the inside edge of the handrail should be at least 2¾" to allow for a secure grip.
This requirement ensures that individuals have adequate space to securely grip the railing which is particularly important for safety and accessibility. It is essential for architects, builders, and inspectors to adhere to this specification to ensure that handrails are usable by people with varying degrees of hand strength and mobility.This requirement ensures that individuals have adequate space to securely grip the railing which is particularly important for safety and accessibility.
