What is the minimum outside diameter for Type 1 handrails that have a circular cross-section?

The minimum outside diameter for Type 1 handrails with a circular cross-section is established to ensure that the handrail is adequately sized for grip and safety. The standard specifies that a diameter of 1-1/4 inches is the minimum for Type 1 handrails. This size provides enough surface area for individuals to securely grasp the handrail, which is crucial for support and stability, particularly in stairways and ramps where users may rely heavily on handrails for balance and coordination. Selection of this diameter ensures compliance with safety regulations while enhancing user accessibility and comfort.
