R5104-59K Toggle Latch with Padlock Hole, SUS201 Stainless Steel, Panel Fastener

NRH R5104-59K Stainless Steel Toggle Latch - Padlock Hole, Vibratory Finish, 15kg Load, Lightweight Security

The NRH R5104-59K is a robust, lockable toggle latch engineered to firmly clamp two panels, doors, or surfaces together while offering optional padlock security. Manufactured from SUS201 stainless steel with a uniform vibratory finishing, it provides excellent corrosion resistance, a smooth satin surface, and burr‑free edges. The over‑center toggle mechanism delivers a reliable 147N (15kg) tensile load for tight, vibration‑resistant closure. An integrated Φ5mm padlock hole allows a standard padlock to be added, physically preventing the latch from opening and providing controlled access. Weighing only 18g and with a compact design (mounting holes 2×Φ4.2mm, overall height approx. 57mm, width 25.5mm), it is ideal for toolboxes, electrical enclosures, machinery guards, and storage cases. 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: overall height approx. 57mm, mounting plate width 25.5mm, main body width 24mm, with 2×Φ4.2mm mounting holes. Padlock hole Φ5mm fits standard padlocks. Refer to the engineering drawing for complete dimensional data.

Why Stainless Steel + Vibratory Finish + Padlock Hole?

SUS201 stainless steel provides a cost‑effective balance of corrosion resistance and mechanical strength, ideal for industrial and outdoor applications. The vibratory finishing process uniformly deburrs edges, creating a smooth, satin surface that is safe to handle, easy to clean, and resistant to fingerprints. The integrated padlock hole is a critical security upgrade:

• Physical theft deterrence - a padlock prevents the latch from being opened without a key
• LOTO compliance - allows padlock to be added for Lockout/Tagout procedures during maintenance
• Tamper evidence - security seals or wire ties can be used for audit trails
• Ready to use - no drilling or modification required

Primary Applications - Secure Clamping with Locking Option

• Toolboxes & equipment cases - tool chests, instrument cases, field kits - secure closure with padlock option
• Electrical enclosures & control cabinets - industrial control panels, server racks, network cabinets - lockable access
• Machine guards & access panels - safety guards, inspection hatches - LOTO ready with padlock
• Storage containers & transport crates - storage boxes, shipping containers - robust lockable closure

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 15kg (147N) clamping force pulls the two surfaces tightly together for a rattle‑free seal. To add security, insert a standard padlock through the Φ5mm padlock hole on the hook. The shackle physically prevents the hook from being lifted, making unauthorized opening impossible without cutting the lock. To release, unlock the padlock then lift the lever.

Key Advantages

• Padlock‑ready security - Φ5mm hole accepts standard padlocks for theft deterrence and LOTO
