Gibraltar G10-0730-G Phenolic Fluted Tapered Knob 3/8-16

Product Description

The GIBRALTAR G10-0730-G is a phenolic female insert fluted tapered knob designed for manual adjustment and control applications across industrial, mechanical, and trade equipment. The knob features a 3/8-16 threaded female insert with a hole depth of 0.75 inches, a 1-inch base diameter, and a 1.375-inch head diameter. Overall length is 4-61/64 inches. Constructed from phenolic material, this knob provides a firm grip surface and solid resistance to heat and chemical exposure in demanding service environments. The black finish and fluted tapered profile make it a standard choice for panel-mount and machine-control installations.

This knob is suited for use on threaded control shafts and adjustment mechanisms found in HVAC equipment panels, electrical enclosures, industrial machinery, and similar trade applications. The female insert mount type allows direct threading onto a 3/8-16 male stud or shaft. It is typically installed during equipment assembly or as a field replacement on existing control hardware wherever a durable, hand-operable knob is required.

Installation Notes

Installation does not require specialized tools — thread the knob onto the 3/8-16 male stud by hand until fully seated to the required depth. Before replacing a knob on active equipment, de-energize the system and confirm all circuits are isolated in accordance with applicable NFPA 70 lockout/tagout procedures. Inspect the receiving stud for thread damage or corrosion before installation. Do not overtighten or use impact tools, as phenolic material can crack under excessive torque.
