Final answer:
The width of a Type II handrail, above the finger recess, must conform to specific measurements to comply with safety and accessibility guidelines, typically ranging from 1¼ inches to 1½ inches.
Step-by-step explanation:
The width of a Type II handrail, above the finger recess, must be 1¼ inches to 1½ inches or 31.75 mm to 38.1 mm. In architectural design and construction, compliance with standards for handrail dimensions is critical to ensure safety and accessibility for users. The Americans with Disabilities Act (ADA) provides guidelines that specify the requirements for handrail dimensions to accommodate individuals with disabilities. Besides the width, other important aspects include the handrail's height, the distance from the wall, and the profile of the railing to ensure a secure grip.
