Gibraltar G10-2837-W Lobed Knob 4 Point Black

Product Description

The GIBRALTAR G10-2837-W is a 4-point lobed knob constructed from thermoplastic elastomer (TPE), offering a firm yet comfortable grip for hand-tightening applications. The knob features a 2.25-inch head diameter and a 3/8-16 threaded stem with 1 inch of thread engagement. TPE construction provides resistance to oils and solvents commonly encountered in mechanical and industrial environments. The black finish is molded throughout the material, not painted, making it resistant to chipping or flaking under regular use. This knob is appropriate for HVAC equipment panels, electrical enclosures, machine guards, and similar assemblies requiring tool-free adjustment or access.

The G10-2837-W is suited for use in light-duty to medium-duty mechanical assemblies where hand-tightened fastening is preferred over tool-driven hardware. Common installation scenarios include equipment access panels, jig and fixture setups, control enclosures, and field-serviceable equipment covers. The 3/8-16 thread is a standard coarse-thread size found across a wide range of industrial and commercial equipment frames and panels. This knob is a single-piece unit, sold individually, with a minimum order quantity of 10 units per purchase.

Compatibility

Designed as a standard replacement or aftermarket hand-knob for equipment and assemblies using 3/8-16 threaded fastener points, including HVAC panels, electrical enclosures, and mechanical fixtures.

Installation Notes

Installation requires no tools — thread the knob onto a compatible 3/8-16 stud or threaded insert by hand until snug. Verify that the mating thread length does not exceed the 1-inch engagement depth of this knob. Power down or de-energize any equipment before servicing panels or enclosures where this knob is used as an access fastener. Do not use impact tools or wrenches on this knob, as over-torquing can damage the TPE body or the threaded insert.
