The Master Lock No. 141D covered solid body padlock features a 1-9/16 inch (40 mm) wide black vinyl covered body for scratch and corrosion resistance. The 1/4 inch (6 mm) diameter shackle is 13/16 inch (21 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.
