Gibraltar G10-3035AW Phenolic 3 Arm Knob Threaded Stem

Product Description

The GIBRALTAR G10-3035AW is a three-arm phenolic knob designed for manual adjustment applications in mechanical, HVAC, electrical, and industrial equipment. The knob features a glossy-coated black phenolic body with a 1.5-inch head diameter and a 7/8-inch overall height. A 3/4-inch threaded stem with a 1/4-20 thread pattern allows direct installation onto compatible threaded shafts or inserts. The 5/8-inch hub diameter provides a solid grip surface at the center. Phenolic construction offers good resistance to heat and electrical conductivity, making it a practical choice for control panels, access doors, and adjustable components in trade equipment.

This knob is suited for use on HVAC equipment panels, electrical enclosures, plumbing service valves, and general mechanical assemblies where a reliable, hand-tightenable fastening point is needed. The three-arm profile gives the installer a firm grip for repeated adjustments without tools. The threaded stem style allows for quick installation and removal during maintenance or service calls. It is commonly used in both residential and light commercial equipment where panel hardware or component adjustment points are required.
