Gibraltar KN6C-B7-21-G Ball Knob Female Insert 1-7/8 in

Product Description

The GIBRALTAR KN6C-B7-21-G is a thermoplastic ball knob with a female insert mount designed for hand-adjustment applications in industrial, mechanical, and trade equipment. The knob measures 1-7/8 inches in diameter and 1-3/4 inches in height, with a 3/8-16 thread size and a hole depth of 5/8 inches. The smooth grip surface and black thermoplastic construction make it a durable, no-tool-required fastening component suited for panel controls, jigs, fixtures, and adjustable assemblies. Technicians and equipment installers use this type of knob wherever a secure, hand-tightened connection is needed without a wrench.

This ball knob is appropriate for use in light industrial and commercial equipment settings where frequent manual adjustment is required. Its female insert design accepts a male-threaded stud or bolt, making it easy to retrofit onto existing hardware. The 3/8-16 thread is a common fastener standard found across a wide range of HVAC equipment panels, electrical enclosures, and mechanical fixtures. One knob is included per package, with a minimum order of two units.

Installation Notes
