Lockable Draw Latch – 76kg Stainless Steel Vibratory | NRH 5104-56K

NRH 5104-56K Lockable Draw Latch - 304 Stainless Steel, Vibratory Finish, 76kg Load, Padlock Hole

The NRH 5104-56K is a lockable, corrosion‑proof draw latch designed for applications requiring both a secure closure and optional physical security. Manufactured entirely from 304 stainless steel with a smooth vibratory finishing, it delivers exceptional rust resistance and a satin, easy‑to‑clean surface. An integrated padlock hole (standard size) allows a security seal or padlock to be added, transforming the latch into a tamper‑evident or theft‑deterrent solution. The over‑center cam mechanism provides a vibration‑proof lock with up to 750N (approx. 76.5kg) of clamping force. Weighing just 21g, it adds negligible mass while delivering robust performance.

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 lock hole sizes, lever lengths, hole patterns, 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. Padlock hole diameter approx. Φ2.4mm (varies by batch - consult drawing). See engineering drawing for precise layout.

Why Lockable Stainless Steel + Vibratory Finish?

304 stainless steel offers intrinsic corrosion resistance - no plating to chip or wear. The vibratory finishing creates a uniform satin surface that is easy to sanitize, resists fingerprints, and has no sharp edges. The padlock hole adds a physical security layer, allowing a padlock or security tie to be attached when the latch is closed. This is essential for:

• Food & pharmaceutical equipment - hygienic, lockable access panels
• Marine & offshore - secure boat compartments, saltwater exposure
• Medical & laboratory - sterilization containers, medication carts, cleanroom furniture
• Industrial & outdoor cabinets - telecom shelters, generator enclosures, chemical storage
• Transport & military - flight cases, weapon storage, ruggedized transit boxes

How It Works - Over‑Center Cam with Lock Hole

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. To secure, insert a padlock through the integrated hole on the lever or base (depending on design) - this physically prevents the lever from being lifted. Release requires unlocking, then lifting the lever.
