The American Lock No. A41 Solid Body Padlock features a 1-1/2in (38mm) wide solid brass body to resist corrosion and a 1-1/2in (38mm) tall, 1/4in (6mm) diameter hardened boron alloy shackle for superior cut resistance. Ideal for harsh environments, a dual ball bearing mechanism resists pulling and prying while a 5-pin APTC12 non-rekeyable cylinder with serrated pins is virtually impossible to pick.
