The NRH 7954-32R is a robust and reliable manual spring pin latch, expertly engineered for secure and tool-free fastening. As detailed in the specifications, it is constructed from SUS201 stainless steel and features a Raw Blank (uncoated) finish, offering inherent corrosion resistance and a clean, industrial aesthetic. Its simple yet effective design consists of an L-shaped pull handle, a high-tension coil spring, and a sturdy base plate. The operation is intuitive: pull the handle to retract the pin against spring pressure for access; release it to allow automatic, spring-driven locking. Weighing only 10g and built for durability, it is an ideal latching solution. Proudly manufactured by NRH Box Hardware, a specialist since 1996, this product is backed by ISO 9001:2000 quality management and complies with SGS, REACH, and SVHC standards. OEM/ODM services are available.

Primary Applications

This versatile latch provides a dependable closure for a wide array of access points:

Professional Tool & Equipment Cases: Secure lids on toolboxes, instrument cases, and field service kits.
Industrial & Electrical Enclosures: Reliable door fasteners for control cabinets, server racks, and modular panels.
Machinery Guards & Safety Covers: Quick-release mechanism for equipment access doors and protective covers.
General Storage & Furniture: Simple locking for cabinets, storage units, and workstations.

How It Works (Operating Principle)

The latch operates on a fundamental spring-loaded principle. The internal compression spring constantly pushes the Ø3.2mm stainless steel pin into the extended (locked) position.

To Unlock: Manually pull the L-shaped handle. This action compresses the spring, retracting the pin completely and allowing the door or panel to swing open.
To Lock: Simply close the door and release the handle. The stored energy in the spring automatically and instantly drives the pin forward, engaging a pre-drilled strike hole or edge to securely lock the assembly with a positive feel.
