NRH R5103-75K Stainless Steel Toggle Latch Padlock Hole Vibratory Finish Lockable

NRH R5103-75K Stainless Steel Toggle Latch - Padlock Hole, Vibratory Finish, 25kg Load, Lockable Security

The NRH R5103-75K is a heavy‑duty, lockable toggle latch engineered for demanding applications requiring superior clamping force and physical security. Manufactured from SUS201 stainless steel with a uniform vibratory finishing, it offers excellent strength, good corrosion resistance, and a smooth, satin, burr‑free surface. The over‑center toggle mechanism delivers a reliable 245N (25kg) tensile load for tight, vibration‑resistant closure. A key security feature is the integrated padlock hole, allowing a standard padlock to be added to physically prevent the latch from opening. Weighing only 34g and with a compact design (mounting holes 4×Φ4.2mm, material thickness 1.3mm), it is ideal for heavy industrial cabinets, machinery guards, and secure 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: mounting holes 4×Φ4.2mm, material thickness 1.3mm. Padlock hole 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 - Heavy Duty with Lockable Security

• Heavy‑duty industrial cabinets & enclosures - electrical switchgear, control panels, server racks - lock to prevent unauthorized access
• Machinery guards & safety covers - secure heavy protective guards with option for safety padlock (LOTO) during maintenance
• Secure storage & transport cases - heavy tool chests, generator cases, ammunition boxes, sensitive equipment transit containers - lockable security
• Outdoor utility & telecom boxes - robust field cabinets for communication or power distribution - 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 or pin and passes its mechanical center point, creating a self‑locking hold that resists vibration and accidental opening. The 25kg (245N) 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.
