The Master Lock no. 40TRI discus padlock features a 1-9/16In (70Mm) 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 3/8In (10Mm) 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.
