Gibraltar G10-3025BB Phenolic 3 Arm Knob 10-32 Black

Product Description

The GIBRALTAR G10-3025BB is a three-arm phenolic knob designed for manual adjustment and control applications in mechanical, electrical, and industrial equipment. Built with a glossy coated phenolic body, this knob offers a hard, durable surface that resists oils, solvents, and general shop wear. The head diameter measures 1-1/8 inches with an overall height of 3/4 inches and a hub diameter of 1/2 inch. A female insert style accommodates a 10-32 threaded fastener with a hole depth of 3/8 inch. The black finish provides a clean, professional appearance. HVAC, electrical, and mechanical trades use knobs like this on control panels, equipment enclosures, and adjustment mechanisms.

This knob is suited for use on control panels, instrumentation, and mechanical assemblies where a secure, hand-operable grip is needed. The three-arm design provides positive finger purchase for frequent adjustments without tools. The female insert thread style makes it compatible with standard 10-32 machine screws commonly found in light-duty trade equipment, panel assemblies, and enclosure hardware. The compact profile fits applications where clearance around the mounting surface is limited.
