Gibraltar G10-3025AT Phenolic 3 Arm Knob 8-32

Product Description

The GIBRALTAR G10-3025AT is a three-arm phenolic knob designed for use with threaded fasteners and machine screws in light mechanical and industrial applications. The knob features a glossy-coated black phenolic body with a female insert style, accepting an 8-32 threaded shaft. The head diameter measures 1.125 inches, the overall height is 0.75 inches, the hub diameter is 0.5 inches, and the hole depth is 0.375 inches. Phenolic construction provides good electrical insulation and resistance to oils and solvents commonly encountered in equipment service environments. HVAC technicians, electricians, and equipment maintenance professionals use this style of knob for panel covers, access doors, and control enclosures.

This knob is suited for residential and commercial equipment where a hand-adjustable, tool-free fastening point is needed. Typical applications include control panel covers, junction box lids, equipment access panels, and light machinery guards. The 8-32 female insert accepts standard machine screws, making it a common choice for retrofitting or replacing worn knobs on existing enclosures and equipment frames.

Installation Notes

Installation requires no special tools. Thread the 8-32 machine screw through the mounting surface and engage the female insert by hand.

Verify the panel or enclosure is de-energized before servicing any cover or access point secured by this knob.
