Gibraltar KLS-3-G Locking Knob Plunger 3/8-16 Thread

Product Description

The GIBRALTAR KLS-3-G is a locking knob handle plunger designed for indexing, positioning, and holding applications in industrial and mechanical assemblies. It features a 3/8-16 threaded shank with a 0.75-inch thread length and a knurled locking knob that allows controlled engagement and release of the spring-loaded plunger. The plunger delivers an initial end force of 0.5 pounds and a final end force of 3 pounds, making it suited for light-duty locking and locating tasks. Constructed from steel with a gold zinc chromate finish, this plunger is installed by machinists, millwrights, and mechanical assemblers in equipment panels, fixtures, and jigs.

The KLS-3-G is used in industrial machinery, fabrication fixtures, and mechanical assemblies where a repeatable, hand-operated locking plunger is required. The knurled knob provides a secure grip for tool-free operation in both production and maintenance environments. This style of plunger is commonly found in sheet metal enclosures, machine guards, and adjustable positioning fixtures across light manufacturing and general industrial settings.
