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

NRH R5151-33 Toggle Latch - Spring Loaded, Stainless Steel, Vibratory Finish, 8kg Load, Compact Design

The NRH R5151-33 is a compact, spring‑assisted toggle latch engineered for lightweight to medium‑duty applications where corrosion resistance and reliable closure are essential. Manufactured from SUS 201 stainless steel with a uniform vibratory finishing, it delivers good rust protection and a clean, satin appearance. The integrated spring mechanism assists in both locking and release - push the lever down to engage the over‑center lock, and a slight pull pops it open with spring assistance. Weighing only 7g and with a total height of 35.5mm, it is ideal for space‑ and weight‑sensitive enclosures. The latch is rated for a 78N (8kg) tensile load, making it suitable for small doors, panels, and instrument cases. Clear “NRH” branding ensures quality and traceability.

As a product of NRH Box Hardware (specialist since 1996), this latch is manufactured under an ISO 9001 certified system. Regarding international compliance (SGS, REACH, RoHS, SVHC), these standards can be supported based on customer requirements - contact us for details. OEM/ODM services are available for custom hole patterns, lever lengths, or logo engraving. Full 2D/3D CAD models available upon request.

Key dimensions: total height 35.5mm, mounting holes 4×Φ3.2mm. Refer to the engineering drawing for complete dimensional data.

Why SUS201 Stainless Steel + Vibratory Finish?

SUS201 stainless steel offers good corrosion resistance and mechanical properties at a cost‑effective price point, making it ideal for indoor electronics, instrument cases, and portable equipment. The vibratory finishing process uniformly deburrs the metal, creating a smooth, satin surface that is free of sharp edges and easy to clean. Key benefits:

• Corrosion resistance - withstands humidity and mild chemical exposure
• Aesthetic uniformity - consistent satin finish across all surfaces
• Deburred edges - safe to handle, no risk of cuts
• Low maintenance - easy to wipe clean, resists fingerprints

Primary Applications - Lightweight & Portable Enclosures

• 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 - Spring‑Assisted Toggle Mechanism

This latch utilizes a spring‑loaded toggle action. Pushing the lever down engages the hook with the strike plate, and the over‑center geometry locks it securely - the spring provides a crisp, positive feel. To release, lift the lever slightly; the spring assists in popping it open, making one‑handed operation effortless. The three mounting points (using the 4×Φ3.2mm holes) ensure stable installation even on thin panels.

Key Advantages

• Ultra‑lightweight (7g) - adds negligible mass to portable equipment
• Compact footprint (35.5mm height) - fits tight spaces, ideal for drones and small cases
• Spring‑assisted operation - smooth opening, positive locking, reduced fatigue
• SUS201 stainless steel with vibratory finish - corrosion resistant, clean satin appearance
• 8kg (78N) load capacity - reliable for medium‑small doors and lids
• Precision mounting - 4×Φ3.2mm holes on a stable base pattern
• OEM/ODM ready - custom hole sizes, lever shapes, logo engraving
