The shackle on these padlocks opens with a control key or the combination, which you can set and change at any time. Control keys (sold separately) are required to reset the combination. Made of hardened steel, the shackle is strong and withstands being dropped, tugged, or cut.

Brass-body locks are the most resistant to corrosion but aren’t as strong as zinc-body locks. They have a combination dial on the bottom of the body, so the rolling digits are protected from damage and debris.

Zinc-body locks are stronger than brass-body locks, but they aren't as corrosion resistant. Both ends of the shackle lock inside the body, so they’re harder to break open from prying, shimming, or tapping. They have a combination dial on the side of the body, which makes them easy to grip and open with one hand.

Vertical shackle clearance is greater than 1”. Open shackle one of two ways: With a control key or with the combination, which you can set and change at any time. Control key is sold separately.
