Gibraltar G10-3036-E 3 Arm Knob Thermoplastic Black

Product Description

The GIBRALTAR G10-3036-E is a three-arm thumb knob designed for manual adjustment and control applications across industrial, HVAC, and mechanical equipment. The knob features a textured coated thermoplastic construction with a 1.5-inch head diameter, standing 0.875 inches high, with a threaded stem measuring 1 inch in length. The 3/8-16 threaded stem and 0.625-inch hub diameter make it a practical fastening and adjustment component. Licensed technicians and installers use this type of knob on equipment panels, access doors, duct assemblies, and control enclosures where hand-tightening without tools is required.

This knob is suited for residential and light commercial applications wherever a durable, hand-operated fastener is needed. Common install scenarios include HVAC equipment panels, filter access doors, electrical enclosures, and mechanical controls. The textured surface improves grip in service environments where hands may be oily or gloved. The black finish blends with standard equipment aesthetics and resists minor abrasion in field use.

Installation Notes

Installation is performed by HVAC technicians, electricians, or mechanical service professionals during panel assembly or service access hardware replacement. Ensure the mating threaded insert or stud is clean and undamaged before threading the knob. Hand-tighten only — avoid using tools that could crack or strip the thermoplastic hub. Power down or de-energize any equipment before servicing panels or enclosures where this knob is installed.
