Gibraltar C4-50A-G Revolving Crank Handle Steel

Product Description

The GIBRALTAR C4-50A-G is a revolving crank handle designed for manual actuation of machinery, valves, equipment panels, and other mechanical assemblies requiring rotational input. Built from steel, this handle features a 7/8 inch hub diameter and 7/8 inch hub height, a reamed 1/2 inch bore for secure shaft engagement, and a 1-1/2 inch knob diameter for positive grip. The overall height is 4-3/16 inches with a 5 inch center-to-center dimension. Machinists, millwrights, and maintenance technicians install this type of handle on a wide range of industrial and trade equipment where reliable hand-operated control is needed.

This crank handle suits general industrial and trade applications including machine tool equipment, valve actuators, conveyor controls, and panel assemblies. The reamed bore provides a precise fit on standard 1/2 inch shafts. The steel construction handles moderate-duty mechanical service in both shop and field environments. Suitable for use wherever a compact, low-profile revolving handle is required for manual positioning or adjustment tasks.
