The Master Lock No. 140T Solid Body Padlocks feature a 1-9/16in (40mm) wide solid brass lock body that is strong, durable and resists corrosion. The 1/4in (6mm) diameter shackle is 7/8in (22mm) 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.
