Gibraltar G10-3015-C Fluted Knob 2.5 Inch Phenolic

Product Description

The GIBRALTAR G10-3015-C is a fluted knob with a 2.5-inch head diameter, designed for manual adjustment and control applications across a range of industrial, HVAC, electrical, and mechanical equipment. Constructed from phenolic material with a glossy finish, this knob features a female insert with a 5/16-18 threaded hole size, allowing it to thread onto standard fasteners or control shafts. The phenolic construction provides durability, electrical insulation, and resistance to heat, making it well-suited for panel-mount and equipment-access applications.

The fluted outer profile provides a secure grip for repeated manual operation. The female insert design accepts a threaded stud or bolt, making it compatible with a wide range of standard equipment configurations in both residential and light commercial settings.
