Gibraltar G10-0155 Ball Knob 2 in Threaded Hole Phenolic

Product Description

The GIBRALTAR G10-0155 is a phenolic ball knob with a threaded hole mount, designed for use in industrial and mechanical control applications. The knob measures 2 inches in diameter and 1-13/16 inches in height, with a 5/8-18 threaded hole sized to accept standard threaded stems. Constructed from phenolic material in a matte black finish, it provides a firm, heat-resistant grip surface. The smooth grip style suits applications where a clean, snag-free hand control is needed. Machinists, equipment technicians, and assembly professionals install this type of knob as a manual control handle on machinery, fixtures, jigs, and adjustable mechanical assemblies.

This ball knob is suited for use on machine tools, industrial fixtures, control panels, and adjustable mechanical equipment where a threaded-hole hand knob is required. The 5/8-18 thread size accommodates common threaded stud configurations found on a wide range of industrial equipment. It is appropriate for both light-duty and moderate-duty manual adjustment applications in shop, plant, and field environments. The phenolic construction handles moderate temperature and chemical exposure common in manufacturing and maintenance settings.

Installation Notes

Installation is performed by maintenance technicians or machine assemblers. De-energize and lock out equipment before removing or installing hand knobs on active machinery. Thread the knob onto the mating stud by hand until fully seated, and verify the thread engagement depth does not exceed the 1-3/16 inch hole depth. Do not use power tools to drive the knob onto the stud, as phenolic material can crack under excessive torque.
