Gibraltar LL-5-G Locking L Handle Plunger 1/2-13

Product Description

The GIBRALTAR LL-5-G is a locking L handle plunger designed for indexing, positioning, and clamping applications in industrial and mechanical assemblies. Built with a steel handle and a 1/2-13 thread, it delivers an initial end force of 1 pound and a final end force of 5 pounds, providing a reliable two-stage engagement feel. The plunger body measures 2.11 inches in length with a plunger diameter of 0.31 inches and a plunger projection of 0.75 inches. Machinists, toolmakers, and maintenance technicians install this type of hardware on jigs, fixtures, machine guards, and tooling plates where repeatable manual locking is required.

This plunger suits light-duty industrial and mechanical positioning applications where a compact, hand-operated locking mechanism is needed. The L-shaped handle allows tool-free engagement and disengagement, making it appropriate for frequent-access panels, fixture stops, and positioning components in both production and maintenance environments. The 1/2-13 thread size allows installation into standard tapped holes found across a wide range of metal fabrications and equipment frames.

Key Features

• Locking L handle design allows tool-free, repeatable engagement and release
• 1/2-13 thread with 1.1 inches of thread length for secure installation in standard tapped holes
• Two-stage force profile: 1 pound initial end force to 5 pounds final end force
• Plunger diameter of 0.31 inches and projection of 0.75 inches suited to light-duty indexing
• Steel handle construction for durability in industrial environments
• Compact body length of 2.11 inches for use in space-constrained assemblies

Compatibility

Designed as a standard replacement or new-installation locking L handle plunger for equipment and fixtures using a 1/2-13 tapped hole interface.

Installation Notes

Install into a clean, properly tapped 1/2-13 hole using the integrated hex feature for final torque — a standard open-end or box wrench sized to the 0.5 inch hex is appropriate. Ensure the mating hole depth accommodates the full thread engagement length before installation. Verify the plunger bore alignment with the indexing feature in the mating component before tightening. No special certifications are required for installation, but follow applicable machine safety lockout/tagout procedures when servicing equipment that uses this plunger.
