Gibraltar 5B50F206A8Z001G Lobed Knob 5-point Black

Product Description

The GIBRALTAR 5B50F206A8Z001G is a 5-point lobed knob designed for manual adjustment and control applications across trade and industrial equipment. Molded from thermoplastic elastomer, this knob delivers a firm, slip-resistant grip while maintaining flexibility under varying temperatures. It features a 5/16-18 threaded stem hole, a head diameter of 1.91 inches, and an overall height of 1.09 inches. The black finish is standard for panel and equipment hardware. Technicians and installers use lobed knobs in control panels, HVAC equipment, electrical enclosures, and light mechanical assemblies where frequent hand adjustment is required without tools.

This lobed knob is suited for residential and commercial applications where a secure, tool-free grip point is needed on adjustment shafts, threaded studs, or machine screws. Common install scenarios include control panel face hardware, access door latches, equipment covers, and field-serviceable assemblies. The 5/16-18 thread size is a widely used standard in trade equipment, making this knob a practical replacement or new-install hardware component for HVAC, electrical, and mechanical panel work.
