The Master Lock Laminated Padlock features a 1-3/4in (44mm) wide laminated steel body for maximum strength and reliability. The 5/16in (8mm) diameter shackle is 2in (51mm) long and made of hardened steel, offering extra resistance to cutting and sawing. The 4-pin cylinder prevents picking and the dual locking levers provide resistance against prying and hammering. The Limited Lifetime Warranty provides peace of mind from a brand you can trust.
