R5104-59K Toggle Latch with Padlock Hole, Nickel Plated, Panel Fastener

NRH R5104-59K Lockable Toggle Latch - Padlock Hole, Nickel Plated, 15kg Load, Spring Assisted

The NRH R5104-59K is a robust, lockable toggle latch engineered to provide secure mechanical fastening with the option for added security using a standard padlock. Constructed from SPCC cold‑rolled steel with a bright nickel plating finish, it offers good strength, corrosion resistance, and a professional silver appearance. The spring‑assisted 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 being opened and providing controlled access. Weighing only 19g and with a compact size (overall height 59mm, length 44mm, width 27mm, mounting holes 4×Φ4.2mm), it is ideal for toolboxes, industrial panels, outdoor enclosures, and transport 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 59mm, length 44mm, width 27mm, with 4×Φ4.2mm mounting holes. Padlock hole Φ5mm fits standard padlocks. Refer to the engineering drawing for complete dimensional data.

Why Nickel Plated Steel + Padlock Hole + Spring Assist?

SPCC cold‑rolled steel provides excellent strength and formability at a cost‑effective price point. The nickel plating adds a bright, corrosion‑resistant surface that outperforms standard zinc plating in many industrial environments. The internal spring assist ensures smooth, consistent operation with positive tactile feedback, reducing user effort. 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 & storage chests - secure toolboxes, equipment cases, storage units - add a padlock for asset security
• Industrial panels & access doors - service hatches, control panel doors, machine guards - LOTO ready
• Outdoor enclosures & utility boxes - communication cabinets, electrical boxes - visible theft deterrent
• Transport cases - shipping containers, equipment cases - seal with padlock during transit

How It Works - Spring‑Assisted Over‑Center Toggle with Padlock Hole

The latch operates on a classic over‑center toggle mechanism enhanced by an internal spring. When the lever is pressed down, the spring helps draw the hook past 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 latch body (or hook). The shackle physically prevents the lever from being lifted, making unauthorized opening impossible without cutting the lock. To release, unlock the padlock then lift the lever. The nickel‑plated steel construction ensures long‑term reliability in demanding environments.
