The Master Lock 141DLF Covered Solid Body Padlock features a 1-9/16in (40mm) wide black vinyl covered body for scratch and corrosion resistance. The 1/4in (6mm) diameter shackle is 1-1/2in (38mm) 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.
