These locks have a plastic body that resists corrosion and won’t scratch or damage nearby surfaces. A name tag on one side means these locks double as a luggage ID.

Shoulders cover most of the shackle, making it difficult to access and cut. The shackle is hardened steel, so the exposed part resists cuts better than plain steel. To prevent attempts to force them open from prying, shimming, or tapping, they are dual dead locking, so both ends of the shackle lock inside the padlock body. Because these locks are more secure than standard padlocks, they’re often used for unattended gates or storage for valuable equipment. They unlock with a five-digit combination, which means they have ten times more combinations than four-digit locks for added security. Set or reset your combination at any time.
