Gibraltar SDKL25-PT-G Locking Knob Handle Plunger

Product Description

The GIBRALTAR SDKL25-PT-G is a locking knob handle plunger with a 1/4-20 thread and a Delrin knob. It is a spring-loaded positioning component used to lock or hold adjustable assemblies in place across a range of mechanical and industrial applications. The plunger features a locking element that prevents unintended movement once set. With a body length of 0.63 inches, a maximum plunger diameter of 0.16 inches, and an initial end force of 0.12 pounds ramping to a final end force of 0.36 pounds, this plunger is suited for light-duty indexing and positioning tasks. Mechanical assemblers and maintenance technicians are the typical installers.

This plunger is commonly used in jigs, fixtures, machine tool assemblies, and adjustable industrial equipment where a compact, hand-operable locking mechanism is required. Its Delrin knob allows tool-free operation, making it practical for assemblies that require frequent manual adjustment. The 1/4-20 thread provides broad compatibility with standard threaded housings and panels found in light mechanical fabrication and equipment manufacturing environments.

Compatibility

Designed as an OEM-style replacement or direct-fit component for assemblies using 1/4-20 threaded locking plungers in light-duty mechanical and industrial fixture applications.

Installation Notes

Installation is typically performed by mechanical assemblers or maintenance technicians familiar with threaded fastener components. Ensure the mating threaded housing is clean and free of debris before threading in the plunger body. Do not exceed the rated end force range, as over-compression can damage the internal spring or locking element. No special tools are required for installation or knob operation.
