R5101-105K SUS201 Stainless Steel Spring Toggle Latch with Padlock Hole, Heavy Duty Industrial Fastener

NRH R5101-105K Heavy Duty Toggle Latch - Padlock Hole, 40kg Load, Stainless Steel, Industrial Security

The NRH R5101-105K is a heavy‑duty industrial toggle latch that combines strong mechanical clamping with physical theft deterrence. Manufactured from SUS201 stainless steel with a uniform vibratory finishing, it offers excellent strength, corrosion resistance, and a smooth, burr‑free surface. The core security feature is the integrated padlock hole on the latch hook - allowing a standard padlock to be added, upgrading security from “fastened” to “physically locked.” The over‑center mechanism delivers a powerful 392N (40kg) tensile load for tight, vibration‑resistant closure. Weighing 80g and with a compact footprint (overall height 106mm, mounting plate width 40mm), it is ideal for high‑value industrial cabinets, machinery guards, and outdoor enclosures. 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, CNAS), 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: overall height 106mm, mounting plate width 40mm, mounting plate length 20.5mm, hook span 47.5mm, material thickness 1.4mm, with 4×Φ5mm mounting holes. Refer to the engineering drawing for complete dimensional data.

Why SUS201 Stainless Steel + Padlock Hole?

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. The integrated padlock hole is a critical security upgrade:

• Physical theft deterrence - a padlock prevents the latch from being opened without a key
• Tamper evidence - security seals or wire ties can be used for audit trails
• LOTO compliance - allows padlock to be added for Lockout/Tagout procedures during maintenance
• No modification needed - the hole is factory‑integrated, ready for standard padlocks

Primary Applications - High Security & Heavy Duty

• High‑value industrial & telecom cabinets - server racks, network cabinets, power distribution units - lock to prevent unauthorized access
• Machinery safety guards & access hatches - secure heavy guards with option for safety padlock (LOTO)
• Outdoor infrastructure enclosures - communication base stations, power control systems, weather‑resistant locking
• Secure tool & material storage - heavy‑duty tool chests, precision instrument cases, maintenance parts bins

How It Works - Over‑Center Toggle with Padlock Security

The latch operates on a classic over‑center toggle mechanism. 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 392N (40kg) clamping force pulls the two surfaces tightly together for a rattle‑free seal. To add security, insert a standard padlock through the integrated hole on the hook. The padlock shackle physically prevents the hook from being lifted, making unauthorized opening impossible without cutting the lock. This dual‑layer security (mechanical latch + padlock) is essential for assets in public, unmonitored, or high‑theft areas.
