Gibraltar G10-3018-A Fluted Knob 3 Inch Phenolic

Product Description

The GIBRALTAR G10-3018-A is a fluted phenolic knob with a 3-inch head diameter and a female threaded insert. It is used to provide a secure, hand-tightened grip point on equipment panels, fixtures, jigs, and industrial assemblies. The knob features a glossy finish over a phenolic body, offering good chemical resistance and dimensional stability in light-duty applications. The female insert accepts a 5/16-18 threaded fastener, making it a standard fit across a wide range of mechanical and trade applications. Licensed tradespeople, maintenance technicians, and equipment assemblers install this type of knob where tool-free adjustment or panel securing is required.

This knob is suited for use in light industrial, HVAC equipment enclosures, electrical panel covers, and general mechanical assemblies where a durable, hand-operated fastening solution is needed. The 3-inch head diameter provides adequate grip surface for repeated hand-tightening without tools. Phenolic construction makes this knob resistant to moderate heat and many common shop chemicals, and the glossy finish provides a clean appearance on finished assemblies or control panels.

Key Features

• 3-inch head diameter provides a comfortable hand-grip surface for tool-free tightening

Installation Notes

This knob is installed by hand or with light assistance from a screwdriver or wrench on the mating fastener. Ensure the receiving thread is clean and free of debris before installation. No power tools are required and overtightening should be avoided to prevent cracking the phenolic body. This type of hardware is typically installed by equipment assemblers, HVAC technicians, or maintenance tradespeople during panel assembly or servicing.
