R5102-90K Heavy Duty Toggle Latch with Padlock Hole, SPCC Nickel Plated, High Load Fastener

NRH R5102-90K Heavy Duty Toggle Latch - Padlock Hole, Nickel Plated, 35kg Load, Industrial Security

The NRH R5102-90K is a heavy‑duty toggle latch that combines high‑strength clamping with physical security. Featuring a prominent padlock hole on the hook, it adds an extra layer of protection for valuable assets. Constructed from SPCC cold‑rolled steel with a bright nickel plating finish, it balances structural strength and corrosion resistance. The over‑center toggle mechanism delivers a powerful 343N (35kg) tensile load for tight, vibration‑resistant closure. Weighing only 56g and with a compact overall length of 90mm and mounting plate width of 39mm, it is ideal for industrial cabinets, machinery guards, and outdoor enclosures that require both high load capacity and padlock security. 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, 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 length 90mm, mounting plate width 39mm, hook height 27.5mm, material thickness 1.2mm, padlock hole diameter Φ5mm. Mounting holes: refer to engineering drawing for exact pattern (typical sizes: Φ5.3mm and Φ5mm).

Why Nickel Plated Steel + Padlock Hole?

SPCC cold‑rolled steel provides excellent formability and strength at a cost‑effective price point. The nickel plating adds a bright, corrosion‑resistant surface that outperforms standard zinc plating in many indoor and sheltered outdoor applications. 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 - High Security & Heavy Duty

• Heavy‑duty industrial & electrical cabinets - power distribution units, automation control cabinets - lock to prevent unauthorized access
• Machinery safety guards & access hatches - secure heavy guards with option for safety padlock (LOTO)
• High‑value tool & equipment cases - precision instrument cases, heavy‑duty tool carts - lockable security
• Outdoor communication & power equipment boxes - base stations, utility boxes - padlock provides theft deterrence

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 35kg (343N) clamping force pulls the two surfaces tightly together for a rattle‑free seal. To add security, insert a standard padlock through the 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.
