These steel lock body padlocks have chrome plating that provides additional protection from harsh weather and corrosive environments, so they can be used both indoors and outdoors. They have solid bodies, which are more secure than laminated bodies because they don't have exposed rivets than can be tampered with. They have a standard shackle that is less than 1.5" in vertical shackle clearance and are keyed different, so all locks open with different keys. Packaging: 1/ea
