Gibraltar G10-0055BJ Ball Knob Threaded Hole Phenolic Red

Product Description

The GIBRALTAR G10-0055BJ is a threaded-hole ball knob designed for manual control and adjustment applications across industrial and mechanical equipment. Molded from phenolic material, this knob offers a firm, heat-resistant grip in a compact form factor. The knob measures 1-15/16 inches in diameter and 1-27/32 inches in height, with a smooth exterior surface. The threaded insert accepts a 5/8-18 thread, with a hole depth of 15/16 inches and a hub diameter of 13/16 inches. The red phenolic construction makes it visually identifiable in multi-control panel setups. Technicians and equipment assemblers working with industrial machinery, control panels, and mechanical fixtures are the primary installers.

This ball knob is suited for use in light to medium-duty manual actuation scenarios, including valve handles, machine controls, and fixture adjustments. The threaded-hole mount style allows direct installation onto a threaded shaft or stud without additional hardware. The phenolic material holds up well under moderate heat and mechanical stress, making it a practical choice for shop environments, equipment panels, and tooling assemblies where a positive hand grip is needed.
