Gibraltar G10-3041-M 3 Arm Knob 2in 5/16-18 Black

Product Description

The GIBRALTAR G10-3041-M is a three-arm thermoplastic knob designed for hand-adjustment applications on machinery, fixtures, and equipment panels. With a 2-inch head diameter and a textured coated finish, the knob provides a secure, no-slip grip without tools. The through-hole female insert accepts a 5/16-18 threaded fastener and offers a 1/2-inch hole depth, making it suitable for standard threaded rod or bolt installations. At 0.035 pounds, it is lightweight and well suited for applications where frequent manual adjustments are required. The black textured coating provides a clean, uniform appearance and added surface grip.

This knob is commonly used in industrial, mechanical, and trade equipment settings where tool-free panel adjustments, clamp tightening, or fixture positioning are needed. Typical applications include HVAC equipment panels, electrical enclosure hardware, pool equipment covers, and general mechanical assemblies requiring a reliable hand-tightened fastener. The 5/16-18 thread size is a standard mechanical thread, making this knob a practical fit across a wide range of equipment types. The 1-inch overall height keeps the knob low-profile in tight-clearance installations.

Installation Notes

Installation requires no special tools — thread the knob onto a 5/16-18 bolt or stud by hand to the required engagement depth, not to exceed the 1/2-inch hole depth of the insert. Ensure the mating threaded fastener is clean and free of debris before installation to avoid cross-threading the thermoplastic insert. Power down or de-energize any equipment panel before installing or removing knobs on live enclosures. Do not use impact tools or wrenches on thermoplastic knobs, as overtorquing will damage the insert.
