Gibraltar G10-3025AU Phenolic 3 Arm Knob Black Gloss

Product Description

The GIBRALTAR G10-3025AU is a three-arm phenolic knob designed for manual adjustment applications in equipment panels, enclosures, and machine assemblies. The knob features a glossy coated finish over a black phenolic body, offering a firm grip surface and resistance to common shop and field conditions. The threaded stem style accepts a 1/4-20 thread, making it compatible with standard fastener hardware found across HVAC equipment access panels, electrical enclosures, and light industrial assemblies. Installed by technicians and assemblers working with control panels, junction boxes, or service access covers, this knob provides a tool-free tightening and loosening solution.

This knob is suited for residential and commercial equipment service panels, electrical enclosures, and instrumentation housings where hand-tightened adjustable fasteners are required. The 1/4-20 threaded stem mounts directly into tapped holes or threaded inserts. The three-arm profile distributes hand torque evenly, reducing the effort needed to secure or release the fastener. It is a standard hardware component used by HVAC technicians, electricians, and equipment service professionals during panel assembly and routine maintenance access.
