Gibraltar G10-3022-C Phenolic 3 Arm Knob 1/4-20

Product Description

The GIBRALTAR G10-3022-C is a three-arm phenolic knob designed for hand-tightening applications on machinery, fixtures, and equipment panels. The knob features a glossy-coated black phenolic body measuring 7/8 inch in head diameter and 3/4 inch in height. A female threaded insert accepts a 1/4-20 fastener, making it compatible with standard machine screws and threaded studs. The hub diameter is 1/2 inch with a 3/8 inch hole depth. Installed by machinists, equipment technicians, and maintenance professionals, this knob provides a firm, ergonomic grip for frequent manual adjustments without tools.

This knob suits light- to medium-duty panel, jig, and fixture applications where a hand-operable fastening point is needed. The three-arm profile distributes grip load evenly and allows for quick tightening and loosening in confined spaces. Common installation environments include industrial equipment enclosures, HVAC access panels, electrical cabinet doors, and shop fixtures. The female insert style means the knob threads directly onto an existing male stud or screw without requiring a through-hole configuration.

Installation Notes

Installation requires no tools beyond hand pressure onto a male 1/4-20 threaded stud or screw. Verify the mating thread is clean and undamaged before seating the knob. Do not use power tools or wrenches to drive the knob onto the stud, as overtorquing can crack the phenolic body. Confirm the stud length does not exceed the 3/8 inch hole depth to ensure full thread engagement.
