Gibraltar G10-0050-B Female Insert Lever Knob

Product Description

The GIBRALTAR G10-0050-B is a female insert lever knob designed for use on threaded shafts and control mechanisms in industrial and trade equipment. The knob features a 1.625-inch head diameter, a 0.656-inch hub diameter, and accepts a 1/4-20 inch threaded insert for secure attachment. With a 0.375-inch hole depth and an overall height of 1.3125 inches, this lever knob provides a firm, ergonomic grip point for manual adjustment applications. It is typically installed by maintenance technicians, equipment assemblers, or HVAC and mechanical service professionals working on control panels, valves, or equipment enclosures.

This lever knob suits applications where a hand-tightened, tool-free adjustment point is needed on 1/4-20 threaded shafts. Common uses include control panel assemblies, HVAC equipment adjustment handles, pump controls, and general industrial machinery. The female insert mount style allows it to thread directly onto a male-threaded shaft or stud, making it a practical component in both OEM assembly and field replacement scenarios.
