Gibraltar G10-0055FB Ball Knob Female Insert Phenolic Red

Product Description

The GIBRALTAR G10-0055FB is a phenolic ball knob with a female insert mount, designed for use as a hand-adjustment control knob on machinery, fixtures, jigs, and industrial equipment. The knob measures 1-15/16 inches in diameter and 1-27/32 inches in height, with a smooth grip surface finished in red. The female insert accepts an M12x1.75 threaded stud or bolt, making it straightforward to install on a wide range of threaded mounting posts. Phenolic construction provides solid rigidity and resistance to common shop chemicals and moderate heat. This part is typically installed by machinists, maintenance technicians, and equipment assemblers.

This ball knob is suited for general industrial and manufacturing applications where a reliable, hand-operated control point is needed. Common uses include machine tool adjustments, clamp handles, fixture positioning knobs, and equipment panel controls. The red color provides quick visual identification on busy shop floors or multi-axis fixtures. The female insert design threads directly onto an existing stud, requiring no additional hardware beyond a properly sized M12x1.75 threaded post. This knob is sold individually, with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by threading the female insert directly onto a properly sized M12x1.75 stud. Before installing or removing the knob, ensure the machine or equipment is powered down and any stored mechanical energy is released. Use thread-locking compound if the application involves vibration that could cause the knob to back off over time. Do not over-torque the knob onto the stud, as phenolic material can crack under excessive force.
