Brass lock body padlocks resist corrosion, so they can be used both indoors and outdoors to restrict access to property. - They have solid bodies, which are more secure than laminated bodies because they don't have exposed rivets that can be tampered with, but they're not as resistant to smashing as steel lock body padlocks. - 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.
