We design our high security padlocks to resist prying, pulling, and picking. Choose a high security padlock for extra protection against physical attacks.
Our general use padlocks offer you peace of mind. When selecting your indoor lock, consider how much security you need. Laminated steel offers greater impact resistance and hardened shackles prevent cutting. You can also choose between combination and keyed locks depending on your preference.
