Gibraltar G10-2837-H Lobed Knob 4-point Black

Product Description

The GIBRALTAR G10-2837-H is a 4-point lobed knob designed for manual adjustment applications where a secure, tool-free grip is required. Molded from thermoplastic elastomer, it provides a firm, comfortable grip surface in black. The knob features a 3/8-16 threaded hole with a 0.5 inch thread depth, a 2.25 inch head diameter, and a 1 inch hub diameter. Overall height is 1 inch. This type of hardware is installed by maintenance technicians, machine builders, and industrial assemblers on equipment panels, fixtures, jigs, and enclosures requiring frequent manual adjustment.

This lobed knob is suited for use on light industrial machinery, tool fixtures, enclosures, and adjustment mechanisms across manufacturing, trades, and equipment maintenance environments. Its thermoplastic elastomer construction provides resistance to oils and mild chemicals common in shop environments. The 3/8-16 thread size is a standard fastener thread found across a wide range of equipment and machine hardware.
