Gibraltar G10-3015 Fluted Knob Phenolic Female Insert

Product Description

The GIBRALTAR G10-3015 is a fluted knob with a 2.5-inch head diameter, designed for use as a hand-tightened fastening or adjustment control in mechanical, industrial, and trade applications. The knob features a female insert threaded at 1/2-13 UNC, allowing it to thread onto a compatible bolt or stud. Constructed from phenolic material with a glossy finish, the G10-3015 offers solid grip and chemical resistance in environments where metal knobs are unnecessary. Licensed tradespeople and equipment technicians install this type of hardware as a replacement or original-fit control knob on panels, covers, and adjustable fixtures.

This knob is suited for use in light industrial, HVAC equipment panels, electrical enclosures, and general mechanical assemblies where tool-free hand adjustment is required. The phenolic construction makes it appropriate for applications where electrical insulation properties are beneficial. It fits anywhere a 1/2-13 threaded female-insert knob is specified for manual operation or panel mounting.

Key Features

• 2.5-inch head diameter for comfortable hand grip
• Female insert with 1/2-13 UNC thread for standard bolt or stud engagement
• Phenolic construction provides durability and electrical insulation
• Glossy finish for a clean appearance on visible panel installations
• Fluted outer profile improves grip during tool-free adjustment

Compatibility

Designed as a replacement or original-fit fluted knob for mechanical panels, enclosures, and adjustable assemblies requiring a 1/2-13 female-insert threaded knob with a 2.5-inch head.

Installation Notes

Installation is typically performed by a technician or mechanic during equipment assembly or panel service. Ensure the mating stud or bolt is clean and free of thread damage before engaging the female insert. No tools are required for standard hand-tightening applications. Verify thread engagement is sufficient to prevent the knob from backing off under vibration or repeated adjustment cycles.
