The American Lock No. AH10 Solid Steel padlock features a 2in (51mm) wide case hardened solid steel body and a 1-1/16in (27mm) tall, 7/16in (11mm) diameter nickel plated hardened boron alloy shackle for superior cut resistance. Dual ball bearing locking mechanism resists pulling and prying and a debris resistant, rekeyable cylinder performs extremely well in external applications.
