Master Lock Company MLK3DLF 40mm Security Padlock

Product Description

The MASTER LOCK COMPANY MLK3DLF is a 40mm wide laminated steel padlock built for high-security applications where cut resistance, pick resistance, and pry resistance are required. The body is constructed from cadmium rustproof laminated steel, providing a tough exterior that holds up against corrosion and physical attack. The shackle is hardened steel with a nickel-plated finish for additional corrosion resistance. A 4-pin cylinder reduces pick vulnerability, while dual locking levers engage the shackle at two points to resist prying. Two brass keys are included. This padlock is suited for trade and commercial security use by facilities technicians, contractors, and security professionals.

The MLK3DLF is appropriate for securing equipment enclosures, tool storage, gate hardware, utility access points, and job site assets. Its laminated steel body construction makes it a practical choice for both indoor and outdoor installations where exposure to moisture or physical abuse is expected. The dual-lever locking mechanism and hardened shackle address common forced-entry methods, making this padlock a reliable choice for light commercial and industrial security contexts.
