Question: 1 / 400

What is the maximum diameter allowed for a circular stairway handrail?

A. 2"

B. 2-1/4"

C. 2-1/2"

The maximum diameter allowed for a circular stairway handrail is 2-1/2". This specification is typically in place to ensure that handrails are both functional and safe. A handrail that is too large can be difficult for users to grip securely, which poses a safety risk, especially in emergency situations.

The 2-1/2" diameter strikes a balance by providing enough surface area for users to hold onto, while also being manageable for different hand sizes. This standard reflects safety regulations and building codes aimed at preventing accidents and ensuring accessibility for all users, including those with disabilities.

Understanding these regulations is crucial for anyone involved in construction or design, as compliance not only affects safety but can also influence inspections and legal liabilities.
