The Master Lock No. 40DPF discus padlock features a 1-9/16 in wide stainless steel body for maximum strength, reliability and corrosion resistance. The fully shrouded design minimizes shackle exposure and protects against bolt cutter attacks. The 3/8 in Dia shackle is 5/8 in 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.
