Gibraltar G10-2820 Lobed Knob 4 Point Phenolic Black

Product Description

The GIBRALTAR G10-2820 is a 4-point lobed knob constructed from phenolic material and finished in a gloss black. Lobed knobs of this type provide hand-tightened clamping and adjustment control in mechanical, industrial, and light equipment assemblies. The 1.5-inch head diameter gives adequate grip surface for tool-free operation. A 1/4-20 threaded hole with 0.375-inch depth allows secure engagement with standard machine screws or threaded studs. Overall height is 1 inch, and the hub diameter measures 0.625 inches. This part is sold individually with a minimum order quantity of 10 units.

This knob is suited for use on jigs, fixtures, machine guards, enclosure panels, and adjustable equipment assemblies where frequent hand adjustment is required. The phenolic construction resists moderate heat and provides electrical non-conductivity, making it a practical choice for light industrial, electrical enclosure, and general mechanical applications. Technicians and fabricators working in shop, manufacturing, or field environments will find this a direct-use hardware component that installs without special tooling.

Installation Notes

Thread the knob onto a 1/4-20 stud or cap screw by hand until snug. Do not use power tools or excessive force, as phenolic material can crack under overtorque. Ensure mating thread engagement does not exceed the 0.375-inch hole depth to avoid bottoming out. No specialized trade certification is required for installation of this hardware component.
