The NRH R7956-10-128 is a long-reach, heavy-duty spring pin latch with a practical stay-open function, designed to streamline maintenance and access workflows. Built from durable SPCC steel and protected with Blue Zinc Plating, it withstands demanding environments. Its defining feature is a precision detent groove on the robust 10mm plunger rod. This allows the latch to be securely held in the retracted position, keeping doors safely open and freeing both hands for tasks inside an enclosure. Closing is effortless: a light push releases the latch, triggering instant, automatic spring-powered locking. With a substantial 128mm overall length and a weight of 144g, it delivers both extended reach and reliable performance. Manufactured by NRH Box Hardware, a trusted manufacturer since 1996. Custom OEM/ODM configurations are available.

Primary Applications

Engineered for efficient, hands-free access in critical environments:

Data Center & Network Maintenance: Perfect for securing server rack doors, network cabinet panels, and PDU enclosures in the open position during hardware installation, upgrades, or cable management.
Industrial Equipment Service: Keeps control cabinet doors, electrical enclosure covers, and machinery guard panels safely open for troubleshooting, calibration, and tool access.
Large Enclosure & Toolbox Access: Allows heavy-duty tool chest lids, welding machine covers, and large equipment case doors to remain upright and stable during organized retrieval of contents.

How It Works: The Stay-Open Advantage

This latch features an intuitive two-stage operation for maximum efficiency and safety.

Secure, Hands-Free Opening: To work inside an enclosure, open the door and fully pull the blue L-handle. The plunger will retract and click into the locked-open detent groove. The door will now remain securely open without needing to be held.
Instant, One-Touch Locking: When finished, a light push on the door or handle releases the plunger from the detent. The internal spring immediately drives the plunger forward, automatically engaging the strike plate and locking the door.
