The Master Lock No. 185D Shrouded Padlock features a 1-15/16in (49mm) 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 9/32in (7mm) diameter shackle is 5/8in (16mm) 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.
