Gibraltar B5-50-G Fixed Handwheel Machine Handle

Product Description

The GIBRALTAR B5-50-G is a fixed handwheel machine handle designed for manual control applications in industrial and commercial equipment. It features a bulb-shape handle measuring 3.75 inches in length with an overall assembled length of 4.5625 inches. The handle mounts via a 1/2-13 threaded stem that measures 0.8125 inches in length. The carbon steel construction on both the handle and stem provides durability under repeated use, while the chrome-plated finish resists corrosion and wear. This type of handle is installed by machine operators, maintenance technicians, and millwrights on valves, jigs, fixtures, and machinery requiring a firm manual grip point.

The B5-50-G suits general industrial machinery, manufacturing equipment, and mechanical assemblies where a fixed, non-folding handwheel handle is required. The 1/2-13 threaded stem is a standard UNC thread size, making it compatible with a wide range of threaded bores on machine components. Applications include clamping mechanisms, feed controls, and adjustment assemblies on lathes, mills, presses, and similar equipment. The bulb shape provides a comfortable grip for frequent or sustained manual operation.

Compatibility

Designed as a replacement or retrofit fixed handwheel machine handle for equipment with a 1/2-13 threaded stem bore. No specific OEM model compatibility is provided in the product data.

Installation Notes

Installation is performed by maintenance technicians or millwrights. Power down and de-energize all equipment before replacing or installing machine handles. Thread the stem into the receiving bore by hand first to verify proper thread engagement before applying a wrench. Avoid over-tightening the stem into aluminum or softer threaded bores to prevent thread damage.
