NRH 5101-96 Toggle Latch | 304 Stainless Steel Black E-Coat Spring Assisted 40kg

NRH 5101-96 Toggle Latch - 304 Stainless Steel, Black Electrophoretic Coating, Spring Assisted, 40kg Load

The NRH 5101-96 is a premium black‑coated toggle latch engineered for applications requiring corrosion resistance, a sleek dark finish, and reliable spring‑assisted operation. Manufactured from 304 stainless steel with a durable black electrophoretic coating (e‑coat), this latch provides excellent protection against rust, chemicals, and wear - all while maintaining a professional matte black appearance. The spring‑assisted over‑center mechanism ensures smooth, one‑handed operation with positive tactile feedback. With a net weight of 85g and a solid 392N (40kg) tensile load, it delivers dependable clamping force for medium‑duty doors, lids, and panels. Clear “NRH” branding ensures traceability and quality assurance.

As a product of NRH Box Hardware (established since 1996), this latch is manufactured under a certified quality management system. Regarding international compliance (ISO 9001, SGS, REACH, RoHS, 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 hole patterns, lever shapes, logo engraving, or alternative finishes. Detailed 2D engineering drawings and 3D CAD models are provided upon request.

Key dimensions: overall length approximately 96mm (as per model number), mounting holes 4×Φ4.5mm, material thickness 1.4mm. Refer to the engineering drawing for complete dimension details.

Why 304 Stainless Steel + Black Electrophoretic Coating?

304 stainless steel offers excellent resistance to oxidation and corrosion, making it ideal for outdoor, marine, and industrial environments. Unlike plated carbon steel, it retains its corrosion resistance even if scratched. The black electrophoretic coating (e‑coat) is applied via an electrodeposition process, creating a uniform, non‑reflective black layer that bonds tightly to the metal. Key benefits:

• Superior corrosion protection - e‑coat provides exceptional resistance to salt spray, moisture, and chemicals, outperforming traditional paint or plating
• Sleek, professional appearance - matte black finish complements dark‑colored equipment, toolboxes, and modern industrial designs
• Scratch and chip resistance - highly durable coating maintains its appearance under frequent use
• Edge coverage - electrophoretic process coats all surfaces, including edges and recesses, preventing rust from starting at unprotected spots

Primary Applications - Versatile for Boxes, Cases, and Cabinets

These black stainless steel toggle latches are super practical for a wide range of enclosures:

• Boxes and cases: Storage boxes, equipment cases, flight cases, instrument cases
• Toolboxes: Professional tool chests, portable tool kits, workshop storage
• Drawers and chests: Filing cabinets, tool chests, treasure chests, hope chests
• Cabinets and closets: Kitchen cabinets, office cabinets, locker doors, wardrobe closets
• Industrial and commercial: Machine guards, electrical enclosures, vending machines, public kiosks

Perfect for use at home, office, shop, garage, and outdoor environments where a black finish and corrosion resistance are desired.

How It Works - Spring‑Assisted Over‑Center Toggle Mechanism

This latch uses a spring‑assisted over‑center toggle mechanism. The lever pivots to engage a hook with a strike plate on the opposing surface. An internal spring helps take up initial slack, providing a smooth, low‑effort start. When the lever is pushed past its mechanical center point, the linkage generates a powerful clamping force that pulls the two surfaces tightly together, creating a rattle‑free seal. The over‑center geometry ensures the latch remains locked under vibration - it cannot open accidentally without deliberate lever lift. To release, simply lift the lever; the spring assists in breaking the over‑center lock, reducing operator effort. This design is ideal for high‑cycle applications such as toolboxes, equipment cases, and access panels.
