Gibraltar G10-3036-C 3 Arm Thermoplastic Knob Black

Product Description

The GIBRALTAR G10-3036-C is a three-arm thumbscrew-style knob made from textured coated thermoplastic, designed for tool-free manual adjustment in panel, equipment, and enclosure applications. The knob features a 1.5-inch head diameter, stands 0.875 inches tall, and accepts a 1/4-20 threaded stem with a 0.5625-inch thread length. A 0.625-inch hub diameter provides a stable grip surface around the stem. The textured finish improves grip in oily or gloved-hand conditions. HVAC techs, electricians, and equipment service professionals encounter this style of knob on access panels, control covers, and adjustable mounting hardware throughout residential and light commercial systems.

This knob is suited for residential and light commercial applications where a low-profile, hand-operated fastener is needed. Common installation scenarios include securing removable access panels on air handlers, electrical enclosures, and equipment cabinets where frequent service access is required. The three-arm profile allows adequate torque without tools in confined spaces. The black thermoplastic construction resists corrosion in interior mechanical environments.

Installation Notes

Installation does not require tools under normal conditions, but a driver may be needed for initial seating in tight clearances. Power down or de-energize any panel or enclosure before removing or reinstalling fasteners that secure access covers. Verify that the 1/4-20 thread specification matches the receiving hardware before installation. Do not overtighten by hand, as thermoplastic hubs can crack under excessive torque.
