Gibraltar MLL-5-G Locking L Handle Plunger M12x1.75

Product Description

The GIBRALTAR MLL-5-G is a locking L-handle plunger designed for use in fixturing, jigs, and machine tooling applications where secure, repeatable positioning is required. Built with a steel handle and a 7mm plunger diameter, this plunger features an M12x1.75 threaded body with a 1.11-inch thread length. The locking mechanism delivers an initial end force of 4.5 N and a final end force of 22.3 N, providing firm hold once engaged. It is installed by maintenance technicians and machine builders who need reliable manual clamping in industrial or shop environments.

This plunger is suited for installation in workholding equipment, tooling plates, fixtures, and positioning assemblies in light industrial and machine shop settings. The L-handle design allows for tool-free hand adjustment, making it practical in production environments where frequent repositioning is needed. The body length of 54mm and a plunger projection of 19mm make it a compact option for tight mounting configurations.

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard M12x1.75 threaded plunger positions in industrial fixtures, tooling plates, and positioning jigs.

Installation Notes

Installation is performed by hand or with a standard wrench using the 12mm hex on the body. Power down and de-energize any associated machinery before servicing or replacing plunger hardware. Ensure the mating threaded bore is clean and free of debris before threading in the plunger body. Confirm plunger projection and locking engagement before returning the fixture or machine to service.
