Gibraltar LL-4-PT-G Locking L Handle Plunger 1/2-13

Product Description

The GIBRALTAR LL-4-PT-G is a locking L handle plunger designed for indexing, positioning, and locking applications in industrial and mechanical assemblies. The plunger features a 1/2-13 thread size with a thread length of 0.85 inches and a body length of 1.5 inches. The locking element holds the plunger in the retracted position, allowing hands-free operation during setup or maintenance. The plunger diameter measures 0.31 inches with a projection of 0.4 inches, and the steel handle construction provides the durability required for repeated use in shop and field environments. Machinists, maintenance technicians, and assembly professionals install this type of component in fixtures, jigs, and machine panels.

This plunger is suited for use in light-duty to medium-duty positioning fixtures where a threaded, spring-loaded plunger with a positive locking feature is required. The L handle configuration allows for easy manual actuation without additional tooling. Typical installations include machine guards, sliding panels, tooling fixtures, and equipment access covers where the operator needs to retract and hold the plunger before repositioning a component. The initial end force of 0.5 pounds and final end force of 2 pounds make it appropriate for applications requiring a firm but manageable engagement force.

Key Features

• Locking element holds plunger retracted for hands-free repositioning
• 1/2-13 thread size with 0.85 inch thread length for secure panel mounting
• Steel handle construction for durability in repeated-use applications
• 0.31 inch plunger diameter with 0.4 inch projection
• Initial end force of 0.5 pounds, final end force of 2 pounds
• Compact body length of 1.5 inches suits space-constrained assemblies

Compatibility

Designed as a standard threaded locking plunger for use in fixtures, jigs, machine panels, and industrial positioning assemblies requiring a 1/2-13 threaded plunger with a locking L handle.

Installation Notes

Installation is performed by threading the plunger body into a tapped hole or nut plate sized for 1/2-13 thread. Ensure the mating panel or component provides adequate thread engagement relative to the 0.85 inch thread length before final tightening. Power down or de-energize associated machinery before servicing or replacing plunger components in live assemblies. No special tools are required beyond a wrench sized for the 0.5 inch hex.
