Gibraltar G10-3035AS Phenolic 3 Arm Knob Black

Product Description

The GIBRALTAR G10-3035AS is a three-arm phenolic knob with a glossy coated finish, designed for use as a manual adjustment or clamping control in light mechanical assemblies. The knob features a 1/4-20 threaded stem for secure engagement with mating fasteners and hardware. It measures 1.5 inches in head diameter, 0.875 inches in overall height, and carries a 0.5625-inch thread length. The hub diameter is 0.625 inches. Constructed from phenolic material, it provides a rigid, durable grip point suited for repeated hand-tightening in industrial, HVAC, and equipment panel applications.

This knob is a standard threaded-stem style intended for use wherever a three-point grip surface is needed for manual adjustment. Typical applications include control panel knobs, equipment guards, jig fixtures, and access covers in commercial and industrial settings. HVAC technicians and equipment service professionals commonly use this style of knob on filter housings, access doors, and adjustment mechanisms. The glossy black finish is suitable for both indoor and light-duty enclosed environments.

Installation Notes

Installation requires no special tools — thread the 1/4-20 stem directly into the mating threaded insert or fastener. Ensure power is removed and any moving equipment is de-energized before replacing knobs on live control panels or equipment covers. Do not use impact tools or exceed hand-tight torque to avoid cracking the phenolic body.
