NRH R5151-33 Toggle Latch | Spring Loaded Stainless Steel Latch | Cabinet Latch

The NRH R5151-33 is a compact and efficient toggle latch made from SUS 201 stainless steel. Featuring a spring-loaded mechanism and a clean vibratory finish, this latch is designed for secure closure on lightweight to medium-duty applications where corrosion resistance and reliable performance are essential.

Primary Applications:

Light Industrial Enclosures: Small control boxes, instrument cases, measurement device housings.
Electronics & Communications: Network equipment cases, server blade enclosures, telecom boxes.
Transportation & Mobility: UAV (drone) cases, portable electronics cases, vehicle glove compartments.
Consumer Products: Small toolboxes, sample cases, custom project enclosures.

How It Works (Operating Principle):

This latch utilizes a spring-loaded toggle action. Pushing the lever down engages the hook with the strike plate, and the over-center action locks it securely. The integrated spring assists in the release action, popping the lever open when disengaged. This design ensures positive latching and easy one-handed operation, with the three mounting points (as per the 4*Φ3.2mm holes) providing stable installation.
