This 3-pack of 2 in. wide padlocks is made out of laminated steel for extra strength. The 3/8 in. diameter, 1 in. long shackle is manufactured from hardened steel for extra resistance to cutting, sawing and prying. Added security feature is a 4 pin cylinder that helps prevent picking. All 3 padlocks are also keyed alike meaning the same key opens all four locks. These padlocks also contain dual locking levers for extra pry resistance. These locks are perfect for residential gates and fences, sheds, workshops, garages, storage lockers, tool chests and tool boxes.
