The A701KA 35852 American Lock Solid Steel Padlock features a 2-1/2"W case hardened solid steel body with a 2"H, 7/16"Dia hardened boron alloy shackle for superior cut resistance. A dual ball bearing locking mechanism resists pulling and prying and a 5-pin APTC12 rekeyable cylinder with serrated pins is virtually impossible to pick.
