Gibraltar 5J55A207A8Z001G Lobed Knob 3-point Tpe Black

Product Description

The GIBRALTAR 5J55A207A8Z001G is a 3-point lobed knob designed for manual adjustment and control applications in industrial and mechanical assemblies. Molded from thermoplastic elastomer (TPE), it provides a firm, comfortable grip even in environments where hands may be wet or gloved. The knob features a 3/8-16 threaded stem hole with a thread depth of 0.91 inches, making it suitable for direct installation onto threaded shafts or studs. At 2.17 inches in head diameter, it delivers adequate torque leverage for finger-tightening applications without tools. Maintenance technicians, equipment assemblers, and field service professionals across HVAC, electrical, and mechanical trades commonly install this type of hardware.

This lobed knob is suited for use on control panels, equipment enclosures, access doors, and mechanical assemblies requiring frequent manual adjustment or removal. It fits any 3/8-16 threaded shaft or fastener and is appropriate for both light industrial and commercial applications. The black TPE construction blends into standard equipment finishes and resists moderate exposure to oils and common shop chemicals. Overall installed height is 1.08 inches, keeping the profile low on the mounting surface.

Installation Notes

Installation requires no special tools — thread the knob onto any compatible 3/8-16 stud or shaft and tighten by hand to the required snugness. Ensure the mating shaft thread is clean and undamaged before installation. Power down or de-energize any equipment before accessing panels or assemblies where the knob will be installed. Do not use impact tools or wrenches on this knob, as excess torque may damage the TPE body.
