Gibraltar LL-3-PT-G Locking L Handle Plunger 3/8-16

Product Description

The GIBRALTAR LL-3-PT-G is a locking L handle plunger designed for indexing, positioning, and locking applications in industrial and mechanical assemblies. The plunger features a 3/8-16 thread with a 1.18-inch thread length and a 0.25-inch diameter steel plunger. Initial end force is 0.75 pounds, with a final end force of 3.75 pounds, giving the user a firm, positive lock once seated. The L-shaped handle provides a low-profile grip for easy manual operation in tight spaces. Machinists, tool-and-die technicians, and industrial maintenance professionals install this type of component in fixtures, jigs, machine guards, and positioning systems.

This locking plunger is suited for light-duty industrial applications where a repeatable, tool-free locking mechanism is required. Common installations include manufacturing fixtures, panel latches, and mechanical positioning assemblies. The 2-inch body length and 0.56-inch plunger projection allow integration into a range of standard fixture designs. The 3/8-16 thread is a widely used coarse-thread standard, making this plunger compatible with a broad set of threaded receiver applications in both production and maintenance environments.

Installation Notes

Installation is performed by threading the plunger into a 3/8-16 tapped receiver by hand or with a wrench on the hex flat. Ensure the receiving thread is clean and free of debris before installation. De-energize or lock out any associated equipment before servicing or replacing plungers in active machinery per applicable lockout/tagout procedures. Do not exceed the rated final end force when torquing the body into the fixture.
