Gibraltar PR25-PT-G Pull Ring Plunger 1/4-20 Steel

Product Description

The GIBRALTAR PR25-PT-G is a steel pull ring plunger with a 1/4-20 thread and a non-locking design suited for positioning, indexing, and locating applications in industrial and mechanical assemblies. The plunger delivers an initial end force of 0.5 pounds and a final end force of 2 pounds, providing reliable spring-loaded retention without requiring a locking element to hold position. The pull ring allows the plunger to be retracted by hand without tools, making it well suited for assemblies that require frequent adjustment. Machinists, millwrights, and maintenance technicians typically install this hardware in jigs, fixtures, machine guards, and panel assemblies.

This pull ring plunger is used in light-duty industrial and mechanical applications where a repeatable, spring-loaded detent or stop point is needed. The 1/4-20 thread allows installation into standard tapped holes in steel, aluminum, or plastic panels. The compact body length of 0.44 inches makes it appropriate for thin-panel or space-constrained mounting situations. It is a single-piece, hardware-level component sold individually.

Key Features

• Pull ring design allows tool-free manual retraction of the plunger
• Non-locking plunger type for easy repositioning without a separate release mechanism
• Steel construction for durability in industrial environments
• Initial end force of 0.5 pounds rising to a final end force of 2 pounds
• Standard 1/4-20 thread fits common tapped holes in panels, fixtures, and frames
• Compact body length of 0.44 inches suits shallow or thin-panel installations

Compatibility

Designed as a standard 1/4-20 threaded pull ring plunger for use in industrial jigs, fixtures, machine panels, and positioning assemblies where a non-locking spring plunger with a pull ring is required.

Installation Notes

Install into a pre-tapped 1/4-20 hole using a wrench on the 0.25-inch hex head. Ensure the mating hole or detent groove is aligned with the plunger tip before fully seating the body. Do not overtighten, as this can restrict plunger travel or damage the spring mechanism. No special trade licensing is required for installation of this hardware component.
