Gibraltar SSTPR38-G Locking Pull Ring Plunger 3/8-16

Product Description

The GIBRALTAR SSTPR38-G is a stainless steel locking pull ring plunger designed for indexing, positioning, and locking applications in mechanical assemblies. The plunger features a 3/8-16 thread with a 1.2-inch thread length, a plunger diameter of 0.233 inches, and a plunger projection of 0.375 inches. Initial end force is 2 pounds, with a final end force of 4 pounds, making it suitable for light-duty retention tasks where a defined force range is required. The pull ring allows manual retraction of the plunger without tools, enabling quick repositioning. This type of hardware is typically installed by mechanical, HVAC, or industrial service technicians in panel, fixture, and equipment assemblies.

The SSTPR38-G is suited for use in residential and commercial equipment panels, jigs, fixtures, and enclosures where a repeatable locking position is needed. The stainless steel construction makes it appropriate for environments with moderate corrosion exposure. It is commonly used in HVAC equipment cabinets, control panel assemblies, and light industrial machinery where tool-free plunger retraction is an operational requirement.

Key Features

• Stainless steel construction for corrosion resistance in demanding service environments
• Locking pull ring allows tool-free manual plunger retraction and repositioning
• 3/8-16 thread with 1.2-inch thread length for secure installation in threaded bores
• Defined force range: 2-pound initial end force to 4-pound final end force

Compatibility

Designed as a direct-fit replacement or new-installation locking pull ring plunger for equipment and assemblies requiring a 3/8-16 threaded indexing plunger with a 0.233-inch plunger diameter and 0.375-inch projection.

Installation Notes

Installation is performed by threading the plunger body into a properly tapped 3/8-16 hole in the mating component. Power down or de-energize any equipment before servicing panels or enclosures that contain this hardware. Confirm thread engagement depth against the 1.2-inch thread length to avoid bottoming out. Standard thread-cutting and hand tools are sufficient for installation.
