Heavy Duty Draw Latch – 76kg Stainless Steel Vibratory | NRH 5104-56

NRH 5104-56 Draw Latch - Stainless Steel, Vibratory Finish, 76kg Load, Industrial Grade

The NRH 5104-56 is a corrosion‑proof draw latch engineered for demanding environments where moisture, chemicals, or hygiene are concerns. Manufactured entirely from 304 stainless steel with a smooth vibratory finishing, it delivers exceptional rust resistance and a satin, easy‑to‑clean surface - no plating to chip or wear. The over‑center cam mechanism provides a secure, vibration‑proof lock: push the lever down, the cam pulls the strike plate tight with up to 750N (approx. 76.5kg) of force; lift to release. Weighing just 21g, it combines high strength with minimal added mass.

Produced by NRH Box Hardware (specialist since 1996) under an ISO 9001 certified system. International compliance (SGS, REACH, RoHS, SVHC) is available upon request - contact us for details. OEM/ODM options include custom hole patterns, lever lengths, or logo engraving. Full 2D/3D CAD models available for integration.

Key dimensions: overall height 70mm, lever length 56.5mm, mounting base 25.5mm wide, with 4×Φ4mm mounting holes. See engineering drawing for precise layout.

Why Stainless Steel + Vibratory Finish?

304 stainless steel is the industry standard for corrosion resistance - it withstands salt spray, acidic cleaners, and high humidity without red rust. Unlike plated carbon steel, the protection is solid throughout, not just a surface layer. The vibratory finishing process deburrs and smooths the metal uniformly, creating a satin, non‑reflective surface that is easy to sanitize, resists fingerprints, and has no sharp edges. This combination is ideal for food processing, medical devices, marine equipment, and outdoor enclosures.

Primary Applications - Harsh Environments Welcome

• Food & pharmaceutical equipment - washdown‑ready latches for processing machinery
• Marine & offshore - boat hatches, deck boxes, saltwater‑exposed enclosures
• Medical & laboratory - sterilization containers, instrument carts, cleanroom furniture
• Industrial & outdoor cabinets - telecom shelters, generator enclosures, chemical storage
• Transport & military - flight cases, ruggedized transit boxes, vehicle toolboxes

How It Works - Over‑Center Cam Action

The one‑piece lever operates a rotating stainless steel cam. When closed, the cam passes its mechanical center point, locking firmly and pulling the strike plate with up to 76.5kg of force. No springs - pure geometry ensures a rattle‑free seal that won't loosen under vibration. Release is a simple lift of the lever. The 56.5mm lever arm provides ample leverage for gloved or wet hands.
