5103-70K SUS304 Stainless Steel Toggle Latch with Locking Hole, Vibratory Polish, Industrial Case Lock

NRH 5103-70K Lockable Toggle Latch - SUS304 Stainless Steel, Vibratory Polish, Padlock Hole, 30kg Clamping Force

The NRH 5103-70K is a lockable toggle latch designed for professional applications where security and cleanability are essential. Crafted from high‑quality SUS304 stainless steel with a fine vibratory polish finish, this latch offers a smooth, burr‑free, and corrosion‑resistant surface. A standard padlock hole integrated into the latch hook provides physical security, while the robust over‑center mechanism delivers a reliable 294N (30kg) clamping force at a lightweight 35g. With detailed engineering drawings (e.g., overall height 70.5mm, mounting plate width 33.5mm, 4x Φ4mm holes), installation is precise and easy.

As a product of NRH Box Hardware (established since 1996), this latch is produced under a certified quality management system. Regarding international compliance (ISO 9001:2000, SGS, RoHS, REACH, SVHC), these standards can be supported based on customer requirements and applicable costs - please contact us for specific certification needs. OEM and ODM services are available for custom applications. For 3D model files or detailed drawings, please contact our team.

Primary Applications - Ideal for Demanding Environments

• Food, beverage and pharmaceutical equipment: Securing inspection windows or access doors on food processing machinery, mixing tanks, and sterilization equipment - meets GMP and wash‑down requirements
• Medical and laboratory instruments: For pharmaceutical refrigerators, sterilization carts, and laboratory instrument cases - providing a clean, lockable, chemically resistant solution
• Marine, naval and outdoor equipment: Locking marine instrument cases, outdoor communication cabinets, and ATV storage boxes - resisting salt spray and humid climates
• Chemical and industrial manufacturing: Used on field control boxes and inspection instrument housings exposed to corrosive atmospheres
• High‑end commercial and professional tool cases: Offering a robust, lockable closure for precision tool carts, metrology calibration cases, and stage audio equipment cases

How It Works - Over‑Center Mechanism with Security

This latch uses an efficient over‑center toggle mechanism with a spring‑assisted action. A simple press on the handle engages the locking arm, pulling two surfaces tightly together and providing positive feedback. The integrated padlock hole on the hook allows a standard padlock to be added, upgrading the closure from “closed” to “locked” - an effective theft‑deterrent for valuable equipment. Lifting the handle releases the clamp, allowing quick access.
