The NRH R7956-10-135 is a premium, extra-long stainless steel spring pin latch, engineered for the most demanding industrial and commercial access applications. As detailed in the technical specification, it is constructed entirely from corrosion-resistant SUS304 stainless steel and finished with a clean Vibratory Finishing, ensuring maximum durability and a professional appearance in harsh environments. The robust design centers on a substantial 10mm diameter solid plunger rod, providing exceptional shear strength. Operation is straightforward and reliable: pull the distinctive blue L-handle to retract the pin; release it to engage powerful, automatic spring locking. Weighing 182g with an extended overall length of 135.5mm, it is built for deep engagement on large, heavy doors and panels. Proudly manufactured by NRH Box Hardware with a legacy of quality since 1996, this product complies with ISO 9001:2000, SGS, REACH, SVHC, and RoHS standards. Full OEM/ODM customization services are available to meet your specific design requirements.

Primary Applications

Designed for superior performance across a wide range of heavy-duty sectors:

Large-Scale Data Center & IT: The ideal latch for deep server rack doors, high-capacity network cabinets, and large PDU/UPS enclosures where secure, reliable access is critical.
Heavy Industrial Machinery & Controls: Provides robust latching for large CNC machine guards, industrial control cabinet doors, welding machine housings, and processing equipment panels.
Outdoor & Harsh Environment Infrastructure: The SUS304 construction makes it perfect for telecommunication shelter doors, outdoor electrical cabinets, marine equipment hatches, and coastal facility enclosures.
Transportation & Logistics for Heavy Equipment: Secure closures for large shipping containers, heavy machinery transit cases, and oversized equipment skids.

How It Works (Operating Principle)

The latch utilizes a simple, heavy-duty spring mechanism for fail-safe operation.

To Unlock: Grasp the blue L-shaped handle and pull it firmly outward. This action compresses the internal high-tension spring, fully retracting the 10mm plunger rod from the strike plate.
To Lock: Align the door or panel with the frame and simply release the handle. The stored energy in the spring automatically and forcefully drives the plunger forward to engage the strike hole, securing the assembly with a definitive, positive action.

Features & Specifications

Corrosion-Resistant SUS304 Construction: Grade 304 stainless steel ensures outstanding resistance to rust, chemicals, and moisture, guaranteeing longevity in the toughest conditions.
Extended 135.5mm Reach: The extra-long body is engineered to securely lock large, deep-set, or insulated doors and panels that standard latches cannot accommodate.
Heavy-Duty 10mm Plunger Rod: The 10mm thick solid stainless steel rod delivers superior shear strength and resistance to bending, built for high-stress applications.
Automatic & Reliable Spring Return: A powerful internal spring guarantees consistent, automatic locking every time the handle is released.
Secure 4-Point Mounting: Designed for maximum stability on heavy doors, featuring a reinforced base plate with 4x Ø3.7mm mounting holes for a vibration-resistant installation.
Ergonomic Blue L-Handle: Provides excellent leverage, a non-slip grip, and clear visual indication of the latch status.
