Non-circular handrails must have a perimeter dimension that is not less than 4" and not greater than what?

Non-circular handrails play an important role in ensuring safety and accessibility in commercial buildings. The requirement for the perimeter dimension of non-circular handrails is critical for providing an adequate grasping surface for users, particularly those who may need to rely on the handrails for support, such as individuals with disabilities.

The specified range for non-circular handrails mandates a minimum perimeter of 4 inches while allowing a maximum of 6-1/4 inches. This upper limit is designed to strike a balance between being thick enough to provide a secure grip but not so wide that it becomes difficult for users to effectively hold onto the handrail. The dimensions have been established in building codes to enhance safety standards and ensure that handrails are functional for a wide range of users.

Understanding the specific limit of 6-1/4 inches helps inspectors ensure compliance with building codes, which is essential for maintaining a safe environment. This particular measurement aligns with current guidelines and best practices in design and construction of handrails in commercial buildings.
