Gibraltar 5B60A205A8Z002G Lobed Knob 5-point Black

Product Description

The GIBRALTAR 5B60A205A8Z002G is a 5-point lobed knob designed for tool-free manual adjustment on threaded fastener applications. Molded from thermoplastic elastomer, it offers a firm yet comfortable grip without hard edges. The knob accepts a 1/4-20 threaded stem with a hole depth of 0.89 inches and an overall height of 1.09 inches. The head diameter measures 2.26 inches, providing sufficient leverage for hand-tightening in confined or accessible panel locations. This type of knob is commonly installed by HVAC technicians, electricians, and equipment assemblers on access panels, enclosures, and control assemblies where repeated manual operation is expected.

This lobed knob is suited for light-duty fastening applications in both residential and commercial equipment. Typical uses include securing removable access doors on electrical enclosures, HVAC cabinets, and control panel covers. The thermoplastic elastomer construction resists minor chemical exposure and provides a non-slip surface in environments where hands may be oily or wet. The 5-lobed profile distributes finger pressure evenly, reducing fatigue during repeated operation.

Installation Notes

Installation requires no special tools — thread the knob onto a 1/4-20 stud or screw by hand. Ensure the mating thread is clean and free of debris before installation. Always de-energize electrical equipment before servicing any panel or enclosure hardware. Do not use power tools to drive this knob, as over-torquing can crack the thermoplastic elastomer body.
