Gibraltar 5B60B931A8Z002G Lobed Knob 5-point Black

Product Description

The GIBRALTAR 5B60B931A8Z002G is a 5-point lobed knob constructed from thermoplastic elastomer (TPE) in a black finish. Lobed knobs are used where tool-free manual adjustment is needed — on equipment panels, access doors, jigs, fixtures, and enclosures across HVAC, electrical, and industrial applications. The knob features a 2.26-inch head diameter and accepts a 5/16-18 threaded stem with 1 inch of thread engagement. TPE construction provides a firm, grippy surface that resists oils and common shop contaminants. Licensed tradespeople and maintenance technicians install these as OEM-style replacements or in custom panel builds where finger-operable fastening is required.

This lobed knob is suited for light-duty manual clamping and adjustment applications in both residential and commercial settings. Typical uses include equipment access panels, instrumentation enclosures, duct damper handles, and fixture clamping assemblies. The 5/16-18 thread is a common unified coarse pitch found on a wide range of equipment frames and threaded inserts. The 5-lobe profile distributes finger grip load evenly, reducing operator fatigue during repeated adjustments. With an overall height of 1.09 inches and a hub diameter of 1.25 inches, it fits in standard panel cutout envelopes without modification.

Installation Notes

Installation requires no special tools — thread the knob onto a 5/16-18 stud or insert by hand. De-energize or shut down any equipment before servicing panels or enclosures where this knob is being installed or replaced. Verify thread engagement depth meets the equipment manufacturer's minimum specification before returning the assembly to service. Do not use power tools to drive or remove TPE lobed knobs, as overtorquing can strip the molded thread insert.
