The Masterlock Laminated Padlock features a rust-resistant lock body, certified by Rust-Oleum. The 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. The dual-armor construction includes a 1-7/8in (48mm) wide laminated steel core with a weather-resistant cover, shackle seals, and keyway cover, protecting against snow, rain, dirt, mud, and grime. The covered keyway and shackle seals offer additional weather protection. The padlock also features dual ball bearing locking for maximum pry resistance and a 4-pin cylinder for increased pick resistance. This padlock comes in a black color and has a size of 48mm. It also comes with a lifetime guarantee.
