The American Lock No. A5570 Solid Brass Padlock features a 2in (51mm) wide solid brass body for superior corrosion resistance in the harshest outdoor or corrosive environments and a 3in tall (75mm), 3/8in (10mm) diameter hardened boron alloy shackle for superior cut resistance. Dual stainless steel ball bearing locking mechanism resists pulling and prying and a rekeyable 5-pin APTC12 brass cylinder with serrated pins is pick resistant and offers tens of thousands of key changes.
