Gibraltar G10-0135-B Ball Knob Female Insert 1 in Phenolic

Product Description

The GIBRALTAR G10-0135-B is a phenolic ball knob with a female insert mount designed for manual adjustment and control applications in industrial and mechanical assemblies. The knob measures 1 inch in diameter with a height of 29/32 inch and features a smooth grip surface. It accepts a 3/8-16 threaded insert with a hole depth of 1/2 inch, making it compatible with standard threaded fasteners and machine bolts. The black phenolic construction offers good chemical resistance and durability in light-duty service environments. Technicians and assemblers use this knob to provide a comfortable, hand-operated grip on levers, fixtures, jigs, and panel-mounted components.

This ball knob is suited for use on machine tools, industrial fixtures, control panels, and adjustment mechanisms where a compact 1-inch knob profile is appropriate. It is commonly installed in manufacturing, mechanical service, and light industrial settings. The female insert style threads directly onto a protruding 3/8-16 stud or bolt, eliminating the need for a separate nut. Its smooth grip and compact hub diameter of 39/64 inch make it practical in tight-clearance installations where larger knobs would interfere with adjacent components.

Installation Notes

This knob is installed by threading it onto a 3/8-16 stud or bolt by hand until snug. Ensure the mating stud does not exceed the 1/2 inch hole depth to avoid bottoming out before the knob seats fully. No special tools are required for typical installation, though thread condition on the mating stud should be inspected before installation. Power down or de-energize any equipment before servicing control or adjustment components.
