The Master Lock no. 3D laminated padlock features a 1-9/16 In. (40 mm) wide laminated steel body for maximum strength and reliability. The 9/32 In. (7 mm) diameter shackle is 3/4 In. (19 mm) 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.
