Gibraltar SSBK-052-G Ball Knob Threaded Hole 1.875 in

Product Description

The GIBRALTAR SSBK-052-G is a stainless steel ball knob designed for threaded-hole mounting applications. Measuring 1.875 inches in diameter with a smooth grip surface, this knob provides a secure, corrosion-resistant handhold for adjustment mechanisms, fixtures, and industrial assemblies. The natural stainless steel finish requires no additional coating and withstands exposure to moisture, cleaning agents, and general shop environments. With a 1/2-13 thread and a 0.75-inch hole depth, it threads directly onto standard fasteners and threaded shafts, making installation fast and tool-free in most cases. Weighing 0.86 pounds, it offers solid feel without excessive bulk.

This ball knob is suited for use in light industrial, HVAC, plumbing, and mechanical equipment applications where a reliable, hand-tightened knob is needed on adjustment rods, jigs, clamps, or control panels. The smooth grip profile works well in clean or lightly oiled environments. Installers and maintenance technicians across multiple trades use this type of hardware to replace worn or missing knobs on equipment panels and access doors.

Installation Notes

Installation is performed by hand or with light tooling — thread the knob onto a 1/2-13 shaft and tighten to a snug, secure fit. Power down or de-energize any equipment before replacing control or adjustment knobs on live panels. Do not use impact tools on this knob, as they can damage the threaded insert or distort the ball body. Follow all applicable equipment manufacturer guidelines and relevant industry codes when servicing mechanical assemblies.
