Gibraltar 5B50A206A8Z002G Lobed Knob 5-point Tpe Black

Product Description

The GIBRALTAR 5B50A206A8Z002G is a 5-point lobed knob made from thermoplastic elastomer (TPE) with a black finish. Lobed knobs provide a firm, comfortable grip for hand-tightening fasteners without tools, making them a common hardware choice on equipment panels, enclosures, fixtures, and assemblies across HVAC, electrical, and general trade applications. The knob features a 1.91-inch head diameter, a 5/16-18 threaded hole, and an overall height of 1.09 inches. TPE construction offers flexibility and resistance to repeated handling. Installation requires no special tools and is performed by hand or with minimal fixture support.

This lobed knob is suited for residential and light commercial applications where frequent manual adjustment or removal of panels, covers, and assemblies is required. The 5/16-18 thread size is a standard fastener specification found across a wide range of equipment and enclosures. Its compact hub and low-profile design make it a practical choice in space-constrained installations where a standard hex nut or bolt head would be difficult to access by hand.

Installation Notes

Installation is performed by hand-threading onto a 5/16-18 stud or bolt. Ensure the mating thread is clean and free of debris before installation. Do not use power tools to drive or remove this knob, as TPE construction is not rated for impact or high-torque power tool use. Power down or de-energize any equipment before servicing panels or enclosures where this knob is used.
