Gibraltar G10-2837-A Lobed Knob 4-point Thermoplastic Elastomer

Product Description

The GIBRALTAR G10-2837-A is a 4-point lobed knob designed for hand-tightening and adjustment applications in industrial, mechanical, and equipment assembly environments. Molded from thermoplastic elastomer (TPE), this knob provides a firm, comfortable grip without tools. It features a 2.25-inch head diameter, a 5/16-18 threaded insert with 0.5 inch of thread depth, and a 1-inch hub diameter. Overall height is 1 inch. The black finish and TPE construction make it resistant to oils and light chemicals encountered in trade and shop environments. Installed by machinists, equipment assemblers, and maintenance technicians.

The G10-2837-A is suited for use on machine guards, fixtures, enclosures, and adjustable equipment panels where frequent hand-operated adjustments are needed. The 5/16-18 thread size is common across a broad range of industrial and mechanical hardware applications, making this knob a straightforward replacement or upgrade for worn or missing adjustment hardware in shop, plant, and field service settings.

Installation Notes

Installation requires no special tools — thread the knob onto a 5/16-18 stud or bolt by hand. Confirm thread engagement depth does not exceed 0.5 inch to avoid bottoming out the insert. Ensure the mating stud is free of debris or damage before installation. Follow applicable equipment lockout/tagout procedures before servicing any machine components.
