Gibraltar G10-2830CG Lobed Knob 4-point Phenolic 2 Inch

Product Description

The GIBRALTAR G10-2830CG is a 4-point lobed knob manufactured from phenolic material in a gloss black finish. Designed for hand-tightening applications, it provides firm, tool-free control in machinery, enclosures, fixtures, and industrial equipment. The knob features a 2-inch head diameter with four evenly spaced lobes that allow consistent grip torque by hand. It mounts on a 1/2-13 threaded stem with a 3/4-inch thread length and a 7/8-inch hub diameter. Overall installed height is 1 inch. Maintenance technicians, machine builders, and equipment fabricators typically install this type of hardware during assembly or field service operations.

This lobed knob suits industrial and commercial applications where frequent manual adjustment is required without tools. Common uses include panel fastening, machine guards, jigs and fixtures, enclosure covers, and adjustable equipment mounts. The phenolic construction resists moderate heat and many common shop chemicals, making it appropriate for light industrial environments. It is sold individually with a minimum order quantity of 10 units.
