NRH 5102-88 Toggle Latch | SPCC Chrome Plated 89kg Heavy Duty

NRH 5102-88 Toggle Latch - SPCC Steel, Chrome Plating, 89kg Load, Heavy Duty Industrial Closure

The NRH 5102-88 is a robust toggle latch engineered for reliable, vibration‑resistant closure in industrial, transport, and enclosure applications. As confirmed by the official specification image, it is manufactured from SPCC steel (cold‑rolled carbon steel) with a bright chrome plating finish - offering excellent corrosion resistance, a professional mirror‑like appearance, and enhanced surface hardness that resists scratches and wear. With a net weight of 59g and a high 875N (89kg) tensile load, this latch delivers substantial holding power for medium‑to‑heavy doors, lids, and panels. The “NRH” logo 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 to streamline your product integration.

Key dimensions: overall length approximately 88mm (as per model number), with 4×Φ4.5mm mounting holes (typical). Refer to the engineering drawing for complete dimension details, material thickness 1.4mm, and exact hole positions.

Why Chrome Plating on SPCC Steel?

SPCC steel offers excellent formability, strength, and cost‑effectiveness. The chrome plating process deposits a thin layer of chromium onto the steel surface, providing several critical advantages:

• Superior corrosion resistance - protects against rust, moisture, and mild chemicals, ideal for indoor and sheltered outdoor applications
• Hardness and wear resistance - chrome reaches 800-1000 HV, significantly harder than bare steel, resisting scratches and repeated cycling wear
• Low friction, smooth operation - the shiny surface reduces friction at pivot points, ensuring consistent lever action over thousands of cycles
• Professional aesthetic - mirror‑like finish matches other chrome‑plated hardware on industrial equipment, toolboxes, and electronics enclosures

For extreme environments (marine, chemical, food processing), we recommend our SUS304 stainless steel variants with vibratory or electropolished finishes.

Primary Applications - Engineered for Medium to Heavy Duty

This latch is suitable for a wide range of enclosures and cases:

• Instrument and equipment cases: Precision instrument protection cases, electronic device housings (communication devices, server chassis)
• Toolboxes and storage: Small to medium toolboxes for professional or household use, portable tool kits
• Industrial enclosures: Machine guards, electrical control cabinets, welding equipment boxes
• Transport and logistics cases: Light transport cases, shipping containers, reusable packaging for logistics

How It Works - Over‑Center Toggle Mechanism

This latch uses a reliable over‑center toggle mechanism. The lever pivots to engage a hook with a strike plate on the opposing surface. When the lever is pushed down, the linkage passes its mechanical center point, generating a powerful clamping force that pulls the door or lid tightly shut. The over‑center geometry ensures the latch remains locked under vibration - it cannot open without deliberate lever lift. To release, simply lift the lever. The design allows for easy one‑handed operation, reducing cycle time in repetitive tasks.

The 89kg (875N) tensile load rating means this latch can withstand significant forces, suitable for medium‑heavy doors, lids that require compression against seals, and equipment subject to transport vibration.
