The GIBRALTAR 5A02B923A8Z002G is a 4-point lobed knob designed for tool-free manual adjustment in light industrial, HVAC, and mechanical assembly applications. Molded from thermoplastic elastomer (TPE), this knob provides a firm yet comfortable grip across a 1.75-inch head diameter. The 1/4-20 threaded stem with a 1-inch thread length allows for straightforward installation onto standard threaded fastener assemblies. At 0.05 pounds, it is lightweight and suited for panel mounting, equipment covers, enclosure latching, and service-access hardware. Technicians and assemblers working with control panels, equipment housings, or service covers will find this a direct-fit replacement or new-installation component.
This lobed knob is commonly used in residential and light commercial HVAC equipment panels, electrical enclosures, plumbing access covers, and general mechanical assemblies where hand-tightened fastening is required. The 4-lobe profile distributes finger pressure evenly, making repeated adjustments practical without tools. The black TPE construction resists minor chemical exposure and normal shop-environment wear.
Designed as a standard 1/4-20 threaded lobed knob compatible with any threaded stud, screw, or insert accepting a 1/4-20 thread in panel, enclosure, and equipment cover applications.
Installation requires no special tools — thread the knob onto a compatible 1/4-20 stud or insert by hand. Ensure the mating thread is clean and free of debris before installation. De-energize or power down any equipment before accessing panels or covers where this knob is being installed or replaced. Do not use power tools to drive this knob, as over-torquing can damage the TPE body or strip the threaded insert.
