Gibraltar 5B60B924A8Z001G Lobed Knob 5-point 1/4-20

Product Description

The GIBRALTAR 5B60B924A8Z001G is a 5-point lobed knob constructed from thermoplastic elastomer (TPE) for reliable hand-tightening in mechanical, HVAC, electrical enclosure, and general equipment applications. With a 2.26-inch head diameter and a 1/4-20 threaded stem, this knob delivers a firm, no-tool grip in service access panels, guards, covers, and fixtures. The TPE material provides resistance to oils and common shop fluids while keeping the knob comfortable to operate in low-clearance or repetitive-adjustment situations. Overall height is 1.09 inches and hub diameter is 1.25 inches. Installed by HVAC technicians, electricians, and mechanical service personnel wherever a secure, removable fastening point is needed.

This lobed knob suits residential and light commercial equipment where frequent hand-adjustment or panel removal is required. Typical applications include access door fastening on air handlers and fan coil units, equipment guard retention, control panel latching, and general fixture assembly. The 5-lobe profile distributes finger load evenly, making it practical for service techs who remove and reinstall covers repeatedly during maintenance calls. The 1/4-20 thread size is among the most common in sheet metal and extruded aluminum equipment frames, broadening its usability across product types.

Installation Notes

Installation requires no special tools — thread the knob onto a 1/4-20 stud or tapped hole by hand. Before servicing any equipment panel or guard secured by this knob, de-energize the equipment per NFPA 70E lockout/tagout procedures. Verify thread engagement across the full 1.25-inch thread length to ensure secure retention. Do not use an impact driver or wrench on this knob, as TPE hubs are not rated for powered tool torque.
