R5102-90 Heavy Duty Toggle Latch, SUS201 Stainless Steel, Vibratory Polish

NRH R5102-90 Heavy Duty Toggle Latch - Stainless Steel, Vibratory Finish, 35kg Load, Industrial Grade

The NRH R5102-90 is a heavy‑duty toggle latch designed for demanding industrial environments requiring reliable, vibration‑resistant closure. Manufactured from SUS201 stainless steel with a uniform vibratory finishing, it offers excellent strength, good corrosion resistance, and a smooth, burr‑free surface. The over‑center toggle mechanism delivers a powerful 343N (35kg) tensile load, securely locking heavy doors, panels, and access covers. Weighing only 55g and with a compact mounting plate width of 38.8mm, it is ideal for large industrial cabinets, machinery housings, and transport equipment. Clear “NRH” branding ensures authenticity and quality.

As a product of NRH Box Hardware (specialist since 1996), this latch is manufactured under an ISO 9001 certified system. Regarding international compliance (ISO 9001, SGS, REACH, RoHS, SVHC), these standards can be supported based on customer requirements - contact us for details. OEM/ODM services are available for custom hole patterns, lever lengths, or logo engraving. Full 2D/3D CAD models available upon request.

Key dimensions: mounting plate width 38.8mm, hook span 41.9mm, with 4×Φ5mm mounting holes. Refer to the engineering drawing for complete dimensional data.

Why SUS201 Stainless Steel + Vibratory Finish?

SUS201 stainless steel provides a cost‑effective balance of corrosion resistance and mechanical strength, ideal for industrial cabinets, machinery guards, and outdoor enclosures. The vibratory finishing process uniformly deburrs edges, creating a smooth, satin surface that is safe to handle and easy to clean. Key benefits:

• Corrosion resistance - withstands humidity and mild chemical exposure
• High strength - 35kg load capacity for heavy‑duty applications
• Smooth, burr‑free finish - safe for frequent handling
• Professional appearance - consistent satin look for visible installations

Primary Applications - Heavy Duty & Industrial

• Heavy‑duty industrial & electrical cabinets - large power distribution cabinets, server racks, industrial automation control cabinets
• Large machinery housings - access panels on machine tools, generator set enclosures, heavy inspection equipment
• Professional transport & storage cases - heavy‑duty tool chests, precision instrument cases, equipment protection cases
• Telecom & energy infrastructure - outdoor communication cabinets, power utility control boxes

How It Works - Over‑Center Toggle Mechanism

The latch operates on a classic over‑center toggle design. When the lever is pressed down, the hook engages a strike plate and passes its mechanical center point, creating a self‑locking hold that resists vibration and accidental opening. The 35kg (343N) clamping force pulls the two surfaces tightly together for a rattle‑free seal. To release, simply lift the lever. The design is proven over thousands of cycles, requiring no lubrication and minimal maintenance. The SUS201 stainless steel construction ensures long‑term reliability even in demanding environments.
