NRH 7954-32R Spring Pin Latch | SPCC Blue Zinc Quick-Release Lock for Toolboxes

NRH 7954-32R Spring Pin Latch - SPCC Blue Zinc, Right‑Hand Opening, 53mm, 4mm Pin

The NRH 7954-32R is a reliable and user‑friendly spring pin latch designed for simple, tool‑free fastening of doors, lids, and access panels. Constructed from durable SPCC steel with a corrosion‑resistant blue zinc plating, this latch offers long‑term reliability. The intuitive spring‑loaded mechanism works as follows: pull the L‑shaped handle to retract the Ø4mm plunger pin for access; release the handle to let the spring automatically extend the pin, securely locking the panel. The “R” suffix indicates optimization for right‑hand opening doors (viewed from the front). Note that the door must swing open away from the side where the handle is mounted.

Weighing only 11g with a compact overall length of 53mm, this latch is a lightweight and space‑efficient solution. The base plate features 2x Ø3.2mm mounting holes spaced at 19mm centers (material thickness: 1.2mm) for simple screw or rivet installation.

The NRH 7954-32R is manufactured by NRH Box Hardware - a trusted manufacturer since 1996 - under an ISO 9001:2000 certified quality management 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 services are available for custom designs.

Typical Applications

• Portable cases and toolboxes (tool chests, instrument cases, field service kits)
• Electrical and industrial enclosures (control panels, server cabinets, junction boxes)
• Machine guards and covers (equipment access panels, safety doors)
• Furniture and storage units (cabinets, lockers, storage compartments)

How It Works - Operating Principle

The latch employs a simple and effective spring‑loaded mechanism. An internal compression spring holds the Ø4mm plunger pin in the extended (locked) position.

• To Unlock: Pull the L‑shaped handle outward. This action compresses the spring and fully retracts the pin from the strike plate or receiving hole. Note: The door must be designed to swing open away from the side where the handle is mounted.
• To Lock: Simply align the door with the frame and release the handle. The spring automatically drives the pin forward to engage the strike hole, securing the door with a positive click.

Key Features & Benefits

• Tool‑Free, One‑Handed Operation: Simple pull‑to‑open, release‑to‑lock action for quick access.
• Automatic & Secure Locking: Internal spring ensures reliable, automatic engagement every time the handle is released.
• Durable SPCC Construction: SPCC steel for strength, with blue zinc plating for corrosion protection.
• Compact & Lightweight: Only 11g net weight and 53mm overall length - minimizes space and mass.
• Easy Installation: Flat base plate with 2x Ø3.2mm mounting holes on 19mm centers for simple screw or rivet mounting.
• Right‑Hand Opening Design: Model suffix “R” indicates configuration for right‑hand doors.
