NRH 7954-50L-1 Spring Pin Latch | 74mm SPCC Blue Zinc Plated Quick Lock

NRH 7954-50L-1 Heavy Duty Spring Pin Latch - Left‑Hand Opening, SPCC Blue Zinc with L‑Handle, 74mm

The NRH 7954-50L-1 is a heavy duty spring pin latch designed for reliable, tool‑free locking on cabinet doors, storage lids, and access panels. Constructed from sturdy SPCC steel with a premium blue zinc plating, this cabinet lock offers excellent corrosion resistance for sustained daily use. The ergonomic L‑shaped handle and internal spring‑loaded plunger enable simple pull‑and‑release operation: pull the handle to retract the Ø4.5mm plunger pin, and release for automatic spring locking. The “L” suffix indicates optimization for left‑hand opening doors (viewed from the front).

Weighing only 18g with a compact 74mm overall length, this latch delivers steady fastening performance in space‑constrained installations. The mounting plate features 2x Ø3.2mm mounting holes spaced at 26.8mm centers (material thickness: 1.2mm) for quick and secure screw fixing.

The NRH 7954-50L-1 is manufactured by NRH Box Hardware - a qualified manufacturer established in 1996 - under an ISO 9001:2008 certified quality control system. Regarding international compliance (SGS, REACH, RoHS, SVHC), these standards can be supported based on customer requirements and applicable costs - please contact us for specific certification needs. OEM and ODM solutions are welcome to match diverse installation demands.

Typical Applications

• Toolboxes and equipment cases (tool chests, instrument cases, portable storage kits)
• Industrial and electrical cabinets (control panels, server racks, modular enclosures)
• Machine guards and access panels (mechanical doors, safety covers)
• Storage furniture and lockers (indoor cabinets, lockers, storage compartments)

How It Works - Easy Operation

Powered by a stable spring‑loaded mechanism, the plunger pin remains locked under normal conditions, driven by an internal compression spring.

• To Unlock: Pull the L‑shaped handle manually to compress the inner spring, retracting the 4.5mm plunger pin and opening the door smoothly.
• To Lock: Close the door and release the handle. The spring instantly pushes the pin forward to fasten the panel securely.

Key Features & Benefits

• Tool‑Free Operation: Pull to open, release to lock - no extra tools required for daily use.
• Automatic Spring Return: Consistent automatic locking ensures safe and firm closure every time.
• Anti‑Rust Steel Build: Solid SPCC steel body paired with blue zinc plating enhances corrosion resistance and service lifespan.
• Compact & Lightweight: 74mm overall length and 18g net weight save mounting space effectively.
• Easy Installation: 2x Ø3.2mm mounting holes with 26.8mm center distance enable quick and stable screw fixing.
• Left‑Hand Opening Design: Model suffix “L” indicates configuration for left‑hand doors.
