Gibraltar BBK-049-G Ball Knob 1-7/8 in Brass Threaded

Product Description

The GIBRALTAR BBK-049-G is a brass ball knob designed for threaded-hole mounting in industrial, mechanical, and trade applications. With a diameter of 1.88 inches and a 3/8-16 thread size, this knob provides a secure, hand-operable grip on levers, jigs, fixtures, machine tools, and equipment panels. The smooth grip surface and natural brass finish make it a straightforward choice for applications where a clean, durable control knob is needed. Licensed tradespeople and maintenance technicians working with machinery, HVAC equipment, or panel assemblies will find this knob a reliable hardware solution.

This ball knob is suited for use in light industrial, commercial, and mechanical service environments. It threads directly onto 3/8-16 fasteners or threaded studs, making it compatible with a wide range of equipment requiring hand-adjustable control points. The 3/4-inch hole depth accommodates standard stud lengths commonly found in equipment panels and fixture assemblies. Typical installation scenarios include control panel knobs, jig and fixture handles, and machine adjustment points in both shop and field environments.

Installation Notes

Installation requires no special tools beyond what is needed to present the mating threaded stud. Power down or de-energize any equipment before replacing control knobs on live panels or machinery. Verify that the mating stud thread is 3/8-16 and that stud protrusion does not exceed the 3/4-inch hole depth to ensure full thread engagement. This type of hardware is typically installed by maintenance technicians, millwrights, or HVAC service professionals during equipment assembly or repair.
