Gibraltar G10-0155-A Ball Knob Female Insert 2 in

Product Description

The GIBRALTAR G10-0155-A is a phenolic ball knob with a female insert mount designed for use on machines, fixtures, and industrial equipment where a secure, hand-tightened grip is required. The knob measures 2.0 inches in diameter and 1-13/16 inches in height, with a smooth exterior finish in black phenolic. The female insert accepts a 3/8-16 threaded stem, with a hole depth of 1/2 inch and a hub diameter of 1-1/16 inch. Phenolic construction provides good resistance to oils, solvents, and heat encountered in typical shop and manufacturing environments. This knob is installed by maintenance technicians, machine operators, and equipment assemblers.

This ball knob is suited for use on machine tool handles, jig and fixture assemblies, panel controls, and general industrial hardware applications where a compact, hand-operated knob is needed. The 3/8-16 thread size is a common standard fastener size, making this knob broadly applicable across light and medium industrial equipment, tooling setups, and fabrication fixtures. The smooth grip style is appropriate for applications where gloves may be worn or where a clean, unobstructed surface profile is preferred.

Installation Notes

Installation does not require specialized tools — thread the knob onto the mating 3/8-16 stud by hand, ensuring the stud does not bottom out before the knob is fully seated against the mating surface. Confirm that the engaged thread length does not exceed the 1/2-inch hole depth to avoid stress on the insert. De-energize or lock out any equipment before replacing or repositioning knobs on moving or powered assemblies.
