Instead of a shackle, this lock has a hook with a latch to make it easier to attach than traditional padlocks. Set your own combination and change it at any time.

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.

Fit the extra-long shackle on these padlocks over large hasps or chains to secure equipment outdoors. They’re made from materials that resist corrosion caused by rain and snow. Set your own combination and change it at any time.

Padlocks with a dual-locking shackle prevent attempts to break them open from prying, shimming, or tapping because both ends of the shackle lock inside the body. Zinc-body locks resist corrosion better than hardened-steel-body locks but aren't as strong. They have an epoxy coating as an extra layer of corrosion protection. It also protects against scuffing nearby surfaces.

Hardened steel shackles are the least corrosion resistant but are stronger than stainless steel shackles. Chrome-plated hardened steel shackles have added strength and an extra layer of protection against corrosion.

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.

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.

No more lost keys or forgotten combinations—these padlocks open with your Bluetooth-enabled smartphone. Download the lock’s corresponding app to register the lock and control it.

More secure than standard padlocks, they have a shackle that’s protected by shoulders, making it difficult to access and cut. Its shackle is made of boron carbide, the hardest and most cut-resistant shackle material. With a body made of powder-coated zinc and a thermoplastic cover, these padlocks are good for outdoor use because they resist rain, snow, and temperature changes.

In an emergency, use a hammer to quickly break the shackle on these locks. They are often used for sprinkler shutoff valves and fire hose housings.
