Gibraltar G10-0025-Q Ball Knob Female Insert 1-1/4 in

Product Description

The GIBRALTAR G10-0025-Q is a phenolic ball knob with a female insert mount, designed for manual adjustment applications on machinery, fixtures, and industrial equipment. The knob measures 1-1/4 inches in diameter and 1-1/4 inches in height, with a smooth grip surface and a black finish. The female insert accepts a 1/4-20 threaded stud with a hole depth of 3/8 inches, making it a direct-thread installation with no tools required for the knob itself. Fabricated from phenolic, it offers resistance to oils, solvents, and moderate heat — properties that make it appropriate for shop and mechanical environments.

This ball knob is suited for light industrial, mechanical, and trade service applications where a low-profile, finger-operated control knob is needed. Typical installations include equipment panels, jig and fixture assemblies, machine guards, and adjustment mechanisms on HVAC, plumbing, and electrical service equipment. The 1/4-20 thread size is among the most common fastener standards in light-duty equipment, making this knob a practical replacement or upgrade for worn or missing original hardware.

Installation Notes

Installation requires a 1/4-20 threaded stud already present on the equipment or panel. Thread the knob onto the stud by hand until snug — do not use power tools, as over-torquing can crack the phenolic body. Power down or de-energize any equipment before servicing adjacent components. Verify hole depth and thread engagement before finalizing the assembly.
