Gibraltar G10-3045-A 3 Arm Knob 5/16-18 Black Thermoplastic

Product Description

The GIBRALTAR G10-3045-A is a three-arm hand knob designed for manual adjustment and control applications across industrial, mechanical, and equipment assembly environments. The knob features a female insert style with a 5/16-18 threaded hole and a 0.5 inch hole depth, making it suitable for threaded stud or screw engagement. It measures 2.5 inches in head diameter and 1.25 inches in height, with a hub diameter of 0.8125 inches. Constructed from textured coated thermoplastic, the knob provides a firm, non-slip grip and resists corrosion in light-duty service conditions. The black finish gives it a clean, functional appearance suitable for visible panel or equipment applications.

This knob is used in a wide range of applications where tool-free manual adjustment is required. Typical installations include control panels, machinery covers, fixtures, enclosures, and adjustment mechanisms in HVAC equipment, industrial machinery, and electrical panels. The three-arm design distributes hand pressure evenly, allowing sufficient torque to be applied without tools. It is commonly installed by maintenance technicians, equipment assemblers, and field service personnel during both original equipment builds and replacement service calls.

Compatibility

Designed as an OEM-style replacement or original-fit hand knob for equipment and panel assemblies requiring a 5/16-18 female threaded insert knob with a three-arm thermoplastic body.

Installation Notes

Installation requires no special tools — the knob threads directly onto a 5/16-18 male stud or cap screw. Ensure the mating thread is clean and free of debris before engagement. Do not overtighten, as the thermoplastic body can crack under excessive torque. Power down or de-energize any equipment before servicing panels or assemblies where this knob is being replaced.
