Gibraltar SSBK-049-G Ball Knob Threaded Hole 1-7/8 in

Product Description

The GIBRALTAR SSBK-049-G is a stainless steel ball knob with a threaded hole mount, designed for use as a control or adjustment knob on machinery, equipment panels, and fixtures across industrial and trade applications. Measuring 1.875 inches in diameter with a 3/4-inch hole depth and a 3/8-16 thread size, this knob provides a secure, corrosion-resistant grip point for manual adjustments. The smooth grip surface and natural stainless steel finish make it well suited for environments where cleanliness and durability are priorities. Licensed technicians and equipment maintenance professionals install this type of hardware during machine assembly, panel fabrication, or field servicing.

This ball knob is appropriate for residential and commercial applications wherever a threaded control point is needed on HVAC equipment panels, plumbing fixtures, pool equipment enclosures, or general mechanical assemblies. The 3/8-16 thread is a widely used standard size, making this knob compatible with a broad range of threaded hardware applications. It is sold individually and is suitable for both original installation and replacement of worn or damaged knobs.

Installation Notes

Installation requires threading the knob onto a compatible 3/8-16 stud or bolt by hand or with a strap wrench if additional torque is needed. Always power down or de-energize equipment before servicing panels or replacing control hardware. Verify thread engagement depth does not exceed the 3/4-inch hole depth to avoid bottoming out on the stud. Follow applicable equipment manufacturer guidelines and local mechanical codes when replacing hardware on pressurized or energized systems.
