The Master Lock Padlock features a 2in (51mm) wide chrome plated solid steel lock body that is strong, durable and resists rust and corrosion. The 9/32in (7mm) diameter shackle is 15/16in (24mm) long and made of hardened steel, offering extra resistance to cutting and sawing. The 5-pin cylinder prevents picking and the dual locking ball bearings provide maximum protection against prying and hammering. The Limited Lifetime Warranty provides peace of mind from a brand you can trust.
