The American Lock No. A5530 Solid Brass Padlock features a 1-1/2in (38mm) wide solid brass body for superior corrosion resistance in the harshest outdoor or corrosive environments and a 1in (25mm) tall, 1/4in (6mm) diameter chrome plated, 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.
