NRH R7956-10-135 is a professional-grade heavy-duty spring pin latch engineered for reliable manual fastening in industrial environments. Constructed from SPCC steel with a durable blue zinc plating, it resists corrosion and withstands heavy use. The ergonomic L-shaped pull handle and integrated spring mechanism enable tool-free operation - simply pull to retract the 10mm solid steel plunger and release for automatic spring-loaded locking. Weighing 183g with an overall length of 135.5mm, this latch delivers extended reach and exceptional shear strength. Manufactured by NRH Box Hardware (specialist since 1996) under an ISO 9001:2000-certified quality system, and fully compliant with SGS, REACH, RoHS, and SVHC standards. OEM/ODM services are available for custom requirements.
Primary Applications
This robust latch is designed for securing large and heavy-duty access points in demanding sectors:
- Large Industrial Cabinets & Server Racks: Ideal for extra-large server cabinets, data center enclosures, and power distribution units.
- Heavy Machinery & Equipment Guards: Perfect for machine tool enclosures, industrial welding equipment cases, and substantial safety guards.
- Transportation & Logistics Cases: Secure closures for heavy-duty shipping containers, large equipment transit boxes, and flight cases.
- Energy & Utility Enclosures: Reliable door latching for outdoor electrical cabinets, transformer enclosures, and telecom infrastructure boxes.
How It Works (Operating Principle)
The latch operates on a robust spring-loaded mechanism. An internal compression spring holds the plunger pin firmly in the extended (locked) position:
- To Unlock: Pull the L-shaped handle outward. This compresses the spring and fully retracts the 10mm pin, clearing the strike plate.
- To Lock: Align the door and release the handle. The spring automatically drives the pin forward into the strike point, securing the door positively.
