NRH 5104-56 Draw Latch - Marine Grade 316 Stainless Steel, Vibratory Finish, 25kg Load, Saltwater Ready
The NRH 5104-56 is a premium draw latch engineered for the most corrosive environments - offshore platforms, chemical plants, marine vessels, and coastal infrastructure. Manufactured from SUS316 stainless steel (marine grade) with a uniform vibratory finishing, it delivers exceptional resistance to salt spray, chlorides, acids, and industrial chemicals - outperforming standard 304 in aggressive conditions. The over‑center cam mechanism provides a reliable, vibration‑proof lock with a 245N (25kg) tensile load - sufficient for medium‑duty doors, hatches, and access panels. Weighing just 23g, it combines robust corrosion protection with lightweight design.
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 56mm, mounting base 25.5mm wide, with 4×Φ4mm mounting holes. See engineering drawing for precise layout.
Why SUS316 Marine Grade Stainless Steel?
Standard 304 stainless steel resists corrosion in many environments, but fails in saltwater or heavy chemical exposure. SUS316 contains molybdenum (2-3%), which dramatically improves resistance to pitting and crevice corrosion caused by chlorides (salt). This makes the 5104-56 ideal for:
- Marine & offshore - boat hatches, deck boxes, dock equipment, shipboard cabinets
- Chemical & industrial processing - valves, pump covers, mixing tanks, washdown stations
- Coastal infrastructure - telecom shelters, power cabinets, outdoor lighting enclosures
- Medical & pharmaceutical - sterilization equipment where aggressive cleaning agents are used
- Food processing - high‑humidity, salt‑laden environments (e.g., seafood processing)
The vibratory finishing process uniformly deburrs and smooths the surface, creating a satin, easy‑to‑clean finish that resists bacterial adhesion and has no sharp edges - ideal for sanitary applications.
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 25kg 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 56mm lever arm provides ample leverage for gloved or wet hands.
Key Advantages
- Marine grade SUS316 stainless steel - maximum corrosion resistance in saltwater and chemical environments
- 25kg (245N) holding force - reliable for medium‑duty doors, hatches, and access panels
- Vibratory finish - smooth, satin, burr‑free, easy to clean, sanitary
- Ultralight - 23g - negligible weight penalty for portable or marine equipment
- Precision mounting - 4×Φ4mm holes on standard centers
- One‑handed operation - smooth cam action, no sticking
- OEM/ODM ready - custom lengths, hole patterns, logo engraving
