Gibraltar PR25A-PT-G Pull Ring Plunger 1/4-20 Steel

Product Description

The GIBRALTAR PR25A-PT-G is a steel pull ring plunger designed for use in indexing, positioning, and light-duty locking applications across mechanical assemblies, fixtures, and equipment panels. The plunger features a 1/4-20 threaded body that installs directly into a tapped hole, with a pull ring that allows manual retraction of the plunger tip without tools. It delivers an initial end force of 0.5 pounds and a final end force of 2 pounds, providing repeatable spring-loaded engagement. The steel construction offers durability in industrial and commercial environments. Installation requires basic hand tools and fits standard threaded bores.

This pull ring plunger is suited for use in panel assemblies, machine guarding, tooling fixtures, and equipment enclosures where a manually retractable locating or detent function is needed. The non-locking plunger type allows free retraction by pulling the ring, making it appropriate for applications requiring frequent repositioning. Typical installers include millwrights, maintenance technicians, and assembly line personnel working with mechanical positioning hardware.

Compatibility

Designed as a standard 1/4-20 threaded pull ring spring plunger for use in tapped holes on mechanical assemblies, fixtures, panels, and equipment enclosures requiring a non-locking spring-loaded plunger function.

Installation Notes

Installation requires a properly tapped 1/4-20 hole and a 1/4-inch hex wrench or suitable driver to thread the body into place. Power down or de-energize any associated equipment before servicing mechanical assemblies. Do not overtighten the plunger body, as this may affect spring travel and end force. Verify plunger projection and travel clearance within the assembly before final installation.
