Gibraltar G10-4901AJ Ball Knob Female Insert Phenolic Red

Product Description

The GIBRALTAR G10-4901AJ is a phenolic ball knob with a female insert mount, designed for use as a hand-adjustment control on machines, fixtures, and equipment panels. The knob measures 11/16 inch in diameter with a 19/32 inch height and accepts a number 10-32 threaded insert to a hole depth of 3/8 inch. The smooth grip surface and compact form factor make it well suited for applications where frequent manual adjustments are required without tools. The red phenolic body offers good resistance to heat and chemical exposure in light industrial environments. Machinists, assemblers, and equipment maintenance technicians are the typical end users.

This ball knob is used in light industrial and commercial equipment applications where a low-profile, finger-operated control point is needed. Common installations include panel-mounted adjustment screws, jig fixtures, machine guards, and instrument enclosures. The female insert style allows direct threading onto a fixed male stud or bolt already in place on the equipment. The red color aids visual identification of specific adjustment points on multi-control panels.

Installation Notes

Ensure the mating stud is clean and free of burrs before threading to avoid damaging the insert.
