The NRH R7956-10-1-135 is a heavy-duty spring pin latch designed for secure, manual fastening in demanding industrial applications. As detailed in the specification sheet, it is constructed from durable SPCC steel and finished with a protective Blue Zinc Plating for excellent corrosion resistance. Its core feature is a substantial 10mm diameter insert rod, supported by a high-tension coil spring, ensuring reliable shear strength and straightforward operation: pull the rod to retract, release for automatic spring locking. Weighing 135g with an extended total length of 135mm, it is built for robust performance where a long-reach, secure latch is required. Proudly manufactured by NRH Box Hardware, a specialist since 1996, this product is produced under an ISO 9001:2000 certified quality management system and complies with SGS, REACH, SVHC, and RoHS standards. OEM/ODM services are available for custom integration.
Primary Applications
This long-reach latch is ideal for securing larger or deeper enclosures:
-
Industrial Toolboxes & Machine Guards: For large tool chests, welding equipment cases, and machinery with thick access panels.
-
Electrical & Server Enclosures: As a manual fastener for doors on deep control cabinets, server racks, and industrial panels.
-
Transport & Logistics Cases: Provides secure closures for shipping containers and heavy equipment transit boxes.
-
Agricultural & Construction Equipment: Durable locking for vehicle-mounted toolboxes and rugged field service enclosures.
How It Works (Operating Principle)
The latch operates on a reliable spring-loaded principle. The internal compression spring holds the 10mm insert rod firmly in the extended (locked) position.
-
To Unlock: Grasp the blue plastic sleeve on the L-handle and pull firmly outward. This compresses the spring and fully retracts the long rod.
-
To Lock: Align the door or panel and simply release the handle. The spring automatically drives the rod forward over its 135mm length to engage the strike point, securing the assembly with a positive action.
