Stainless Steel Toggle Latch – 10kg Compact Vibratory Finish | NRH 5151-33

NRH 5151-33 Toggle Latch - Stainless Steel, Vibratory Finish, 10kg Load, Compact Size

The NRH 5151-33 is a compact, high‑strength toggle latch engineered for secure closure on small to medium‑sized panels, instrument cases, and electronic enclosures. Manufactured entirely from SUS304 stainless steel with a smooth vibratory finishing, it delivers excellent corrosion resistance, a clean satin appearance, and burr‑free edges. The over‑center toggle mechanism provides a positive, vibration‑resistant lock with an impressive 98N (10kg) tensile load - outstanding for a latch weighing only 7g. With a compact overall height of 35.5mm and a minimal footprint, it adds negligible mass to portable equipment while offering reliable holding power. 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 (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: total height 35.5mm, with 4×Φ3.2mm mounting holes. Refer to the engineering drawing for complete dimensional data (including length, width, and material thickness).

Why SUS304 Stainless Steel + Vibratory Finish?

SUS304 stainless steel is the industry standard for corrosion resistance, ideal for applications exposed to moisture, chemicals, or outdoor environments. Unlike plated steel, it retains its rust resistance even if scratched. The vibratory finishing process uniformly deburrs the metal, creating a smooth, satin surface that is free of sharp edges, safe to handle, and easy to clean. Key benefits:

• Superior corrosion resistance - withstands humidity, salt spray, and mild chemicals
• High strength-to-weight ratio - 10kg load at only 7g
• Smooth, burr‑free finish - no sharp edges, safe for frequent handling
• Professional satin appearance - consistent, attractive look for visible applications

Primary Applications - Small Enclosures & Portable Equipment

• Instrument & electronics enclosures - handheld test equipment, portable measurement devices, sensor housings
• Industrial control panels & access covers - small electrical boxes, inspection hatches, PLC enclosures
• Communication & network equipment - routers, switches, telecom chassis, server blade covers
• Transport cases & toolboxes - lightweight flight cases, sample boxes, hobbyist tool chests

How It Works - Over‑Center Toggle Mechanism

The latch operates on a simple, reliable toggle principle. The mounting base is fixed to one surface, and the pivoting hook engages a strike plate on the opposing panel. When the hook is pressed down, it swings over and passes its mechanical center point, locking securely with a positive snap. This over‑center geometry creates a vibration‑resistant hold that cannot open accidentally. To release, simply lift the hook. The SUS304 construction and vibratory finish ensure smooth, consistent operation for thousands of cycles - no lubrication required.
