Padlock MASTER LOCK M175EURDLH 56mm zinc body 51mm shackle

MASTER LOCK M175EURDLH is a 56mm wide padlock with a durable zinc body and a 51mm long Tough-Cut octagonal boron-carbide shackle. The padlock features a set-your-own 4-digit combination mechanism that offers 10,000 possible combinations and does not require a reset tool. Weather-resistant details include a shackle seal and a hinged dial cover, and the construction includes a reinforced body bumper to reduce scratching.

Advantages

The Tough-Cut octagonal boron-carbide shackle is approximately 50% harder than hardened steel, improving cut resistance. The 51mm shackle length increases mounting options, while the 56mm zinc body with reinforced bumper helps resist scratches. Roller pin locking provides enhanced pick and pry resistance. A one-directional dial aids use in low-light conditions and the padlock is backed by a Limited Lifetime Warranty.
