The Master Lock #141TRILF covered solid body padlocks feature a 1-9/16 in black vinyl covered body for scratch and corrosion resistance. The 1/4 in Dia shackle is 1-1/2 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.
