Protect your valuables with the Masterlock Laminated Padlock, featuring a rust-resistant lock body certified by Rust-Oleum. The lock's tough octagonal boron-carbide shackle is 50% harder than hardened steel, providing added security. The 1-1/2in (38mm) shackle clearance allows for more uses, while the dual-armor construction with a laminated steel core and weather-resistant cover protects against the elements. The lock also features a covered keyway and shackle seals for added weather protection, as well as dual ball bearing locking for maximum pry resistance and a 4-pin cylinder for increased pick resistance. The Masterlock Laminated Padlock is backed by a lifetime guarantee.
