Gibraltar 5A01A205A8Z002G Lobed Knob 4 Point Black

Product Description

The GIBRALTAR 5A01A205A8Z002G is a 4-point lobed knob molded from thermoplastic elastomer (TPE) for tool-free hand tightening and adjustment applications. The knob features a 1.4-inch head diameter with four evenly spaced lobes that provide grip surface for finger torque without tools. The threaded insert accepts a 1/4-20 stem with 0.58 inches of thread engagement depth. At 0.03 pounds, this is a lightweight fastening component suited for panels, enclosures, guards, and adjustment mechanisms across HVAC equipment, electrical panels, and light industrial assemblies.

This lobed knob is used wherever a captive or removable hand-knob fastener is needed on service access panels, equipment covers, filter frames, or adjustable mounting brackets. Its TPE construction provides a degree of grip compliance in both cold and warm environments, making it appropriate for residential and light commercial mechanical equipment rooms, rooftop units, and control panel assemblies where repeated hand-access is required by technicians during service calls.

Installation Notes

Installation is performed by hand-threading the knob onto a 1/4-20 stud or bolt. Power down or de-energize any equipment before accessing panels secured by this knob. Verify that thread engagement depth does not exceed 0.58 inches to avoid bottoming out on the stud. No special tools are required for installation or removal.
