Gibraltar KNL-1-G Knob Handle Plunger 1/4-20

Product Description

The GIBRALTAR KNL-1-G is a non-locking knob handle plunger with a knurled knob, designed for use in mechanical assemblies, jigs, fixtures, and industrial equipment where a spring-loaded positioning or indexing function is needed. It features a 1/4-20 threaded body with a 0.5-inch thread length and a maximum plunger diameter of 0.123 inches. Spring force ranges from 1 pound initial end force to 4 pounds final end force. The body is steel with a gold zinc chromate finish for corrosion resistance. This type of plunger is installed by maintenance technicians, machine builders, and tradespeople working on equipment assemblies requiring repeatable manual actuation.

This plunger is suited for light-duty positioning and indexing applications in industrial, HVAC, or mechanical equipment enclosures. Its compact body length of 0.79 inches and 0.5-inch length under the head make it appropriate for installations with limited clearance. The knurled knob style allows for hand-tightening and actuation without tools, making it practical for panels, access doors, and adjustable components in trade and industrial settings.

Installation Notes

Installation is typically performed by maintenance technicians or machine builders using standard hand tools. Ensure the mating thread in the housing is clean and free of debris before threading in the plunger body. De-energize or lock out any equipment before servicing assemblies that incorporate spring plungers. Do not overtighten, as this may restrict plunger travel or damage the thread.
