To fit around large hasps and thick chains, these padlocks have over 1" of vertical shackle clearance. Multiple locks open with the same key. If the lock or key with the key number you want isn’t listed, order the "Other Key Numbers" and specify your desired key number.

Aluminum-body locks balance strength and corrosion resistance. They’re stronger than zinc-body locks but not as strong as steel-body locks, and they’re more corrosion resistant than both.

Hardened steel shackles are tougher to cut or pry than steel shackles. Those that are copper-nickel-chrome plated have an added layer of corrosion resistance and strength.

Locks with a dual-locking shackle prevent attempts to force them open from prying, shimming, or tapping because both ends of the shackle lock inside the padlock body.

Locks with a pin-tumbler key locking mechanism are harder to pick than locks with a disc-tumbler key locking mechanism. The more pins a lock has, the harder it is to pick.

Style D and E locks have a bumper around the body, so they won’t nearby scratch surfaces.
