The GIBRALTAR G10-2830-E is a 4-point lobed knob designed for manual adjustment applications in industrial, mechanical, and trade equipment. Molded from phenolic material, this knob delivers a firm, gloss-finished grip surface suited for frequent hand operation. The knob seats on a 3/8-16 threaded stem with a 1-inch thread length, providing secure fastening to compatible threaded shafts. With a 2-inch head diameter and a 7/8-inch hub diameter, it offers adequate grip leverage for operators working with panel controls, jigs, fixtures, and similar assemblies. Overall height is 1 inch. This is a single-unit package.
This lobed knob is appropriate for use in light industrial settings, HVAC equipment panels, electrical enclosures, plumbing fixtures, and workshop machinery where tool-free manual adjustment is required. The phenolic construction resists moderate heat and electrical conductivity, making it a practical choice for control panels and equipment requiring hand-tightened fasteners. Installation does not require specialized trade licensing but is commonly handled by maintenance technicians, equipment assemblers, and field service professionals.
Designed as a standard replacement or retrofit lobed knob for equipment using 3/8-16 threaded shafts requiring a 4-point, 2-inch diameter phenolic knob.
De-energize or power down any equipment before replacing control knobs on live panels or electrical enclosures. Thread the knob onto the 3/8-16 stem by hand until snug. Do not over-torque, as phenolic material can crack under excessive force. Verify thread engagement covers the full 1-inch thread length before returning equipment to service.
