Gibraltar LN-1-PT-G L Handle Plunger 1/4-20 Steel

Product Description

The GIBRALTAR LN-1-PT-G is a steel L handle plunger designed for use in positioning, locating, and indexing applications across industrial and mechanical assemblies. The plunger features a 1/4-20 thread size with a 0.8-inch thread length and a body length of 1.25 inches. The plunger tip diameter measures 0.16 inches with a projection of 0.38 inches beyond the body face. End force ranges from 0.5 pounds initial to 2.5 pounds final, providing controlled spring resistance suited for light-duty locking and positioning tasks. A locking element is integrated into the body to hold the plunger in the retracted position when needed.

This plunger is suited for use in machinery, fixtures, tooling, and equipment panels where a compact, threaded index plunger is required. The L-shaped steel handle allows the operator to retract and lock the plunger manually without additional tools. Typical install scenarios include machine guards, slide assemblies, hinged panels, and jig fixtures in manufacturing or maintenance environments. The non-locking plunger tip combined with the body locking element makes it appropriate where the plunger must be held out of engagement during setup and then released into position.

Key Features

• 1/4-20 thread size with 0.8-inch thread length for standard tap-in installation
• Non-locking plunger tip with integrated body locking element to hold retracted position
• 0.5 to 2.5 pound end force range for light-duty indexing and positioning
• Steel L handle with 0.5-inch handle length and 0.09-inch handle diameter
• Compact 1.25-inch body length suitable for space-constrained assemblies
• Plunger projection of 0.38 inches for positive engagement in receiver holes

Compatibility

Designed as a threaded index plunger for use in standard 1/4-20 tapped holes in machine fixtures, tooling plates, and mechanical assemblies requiring spring-loaded positioning or indexing.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped 1/4-20 hole using the 0.25-inch hex on the body. De-energize or lock out any equipment before installing or replacing plungers in active machinery per applicable OSHA lockout/tagout procedures. Verify plunger projection depth aligns with the receiver hole to ensure full engagement under spring load. Do not overtighten the body into the threaded hole, as this can bind the internal spring mechanism.
