Gibraltar G10-3041 3 Arm Knob 2 Inch 1/4-20 Thermoplastic

Product Description

The GIBRALTAR G10-3041 is a three-arm thermoplastic knob designed for hand-tightening and adjustment applications across industrial, mechanical, and equipment assembly environments. The knob features a 2-inch head diameter and stands 1 inch tall, with a textured coated finish that improves grip in oily or wet conditions. The female insert style accepts a 1/4-20 threaded fastener with a 1/2-inch hole depth, allowing secure engagement without through-bolting. Fabricated from thermoplastic with a durable textured coating, this knob is suited for repetitive hand operation and light-duty clamping tasks. Installers and technicians use this type of knob wherever tool-free panel adjustments or equipment control settings are required.

This knob is appropriate for use in control panels, enclosures, jigs, fixtures, and mechanical assemblies where a secure, operator-adjustable fastening point is needed. The 3/4-inch hub diameter and female insert construction make it compatible with standard 1/4-20 threaded studs and bolts. The black textured finish suits both indoor and light industrial outdoor applications. Trades and assembly professionals working on HVAC equipment housings, electrical enclosure covers, and similar panel work commonly install this style of knob as a tool-free adjustment or retention point.

Key Features

• 2-inch head diameter provides comfortable hand grip surface across three lobed arms
• 1/4-20 female insert style accepts standard threaded studs or bolts

• 3/4-inch hub diameter for compact mounting footprint
• Textured coated thermoplastic construction improves grip and resists corrosion
• Black finish suits panel and enclosure applications

Compatibility

Designed for use with 1/4-20 threaded fasteners in standard female insert knob applications. Suitable as a direct replacement for three-arm thermoplastic knobs with equivalent head diameter and thread specifications in industrial and equipment assembly settings.

Installation Notes

Installation requires no tools beyond hand tightening onto a compatible 1/4-20 threaded stud or bolt. Ensure the mating fastener thread length does not exceed the 1/2-inch hole depth to prevent bottoming out and reduce clamping force. Inspect the insert and thermoplastic body for cracks before installation, particularly in high-cycle applications. This knob is intended for hand-operation loads only and should not be torqued with tools.
