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

Product Description

The GIBRALTAR SKLS-1-PT-G is a locking knob handle plunger with a 1/4-20 thread and a 0.4-inch thread length. It features a spring-loaded, locking plunger mechanism designed for indexing, positioning, and holding applications in mechanical assemblies and industrial fixtures. The knurled knob allows for tool-free hand adjustment while the locking element locks the plunger in the retracted position for hands-free operation. Initial end force is 0.5 pounds, with a final end force of 2 pounds. This plunger is installed by maintenance technicians and mechanical assemblers in light industrial, HVAC equipment, and control panel applications.

This locking plunger is suited for use in sheet metal enclosures, control cabinets, machine guards, and access panels where a positive-locking, retractable plunger is needed. The compact form factor and standard 1/4-20 thread make it compatible with a wide range of fabricated steel and aluminum assemblies. It is commonly used in HVAC equipment cabinets, electrical enclosures, and general-purpose mechanical positioning applications where repeatable engagement is required.

Installation Notes

Installation is performed by hand or with a wrench on the threaded shank into a pre-tapped or threaded mounting location.

Verify thread engagement depth against the 0.4-inch thread length to ensure full thread contact without bottoming out. Follow applicable mechanical assembly and equipment manufacturer guidelines during installation.
