Gibraltar SKLS-1-G Locking Knob Plunger 1/4-20 Stainless

Product Description

The GIBRALTAR SKLS-1-G is a locking knob handle plunger designed for indexing, positioning, and clamping applications in industrial and mechanical assemblies. It features a 1/4-20 threaded shank with a 0.4-inch thread length and a stainless steel construction throughout. The plunger diameter ranges from 0.123 to 0.124 inches, with a projection of 0.125 inches and a total plunger length of 0.805 inches. Initial end force is 0.5 pounds, building to a final end force of 2 pounds. The knurled knob head measures 0.5 inches in diameter and 0.28 inches in height, providing a secure manual grip for adjustment and locking. This plunger is installed by maintenance technicians and equipment assemblers in light industrial and trade equipment settings.

The SKLS-1-G is suited for use in panel assemblies, enclosures, jigs, fixtures, and positioning mechanisms where repeatable manual locking is required. The 1/4-20 thread size makes it compatible with standard tapped holes in steel, aluminum, and plastic components. The length under the head or shoulder is 0.53 inches, allowing installation in a range of panel thicknesses. It is sold individually and is appropriate for both original equipment assembly and field replacement of worn or damaged plunger hardware.
