The Master Lock No. 130D Solid Brass Padlock features a 1-3/16” (30 mm) wide solid brass lock body that is strong, durable and resists corrosion. The 3/16” (5 mm) diameter shackle is 5/8” (16 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.
