Secure your luggage and equipment cases when traveling—these locks allow TSA personnel to open your bags without damaging the lock. With more clearance than other locks, they let you thread the shackle or cable of the lock through multiple zipper heads or larger hasps. You can set your own combination and change it at any time.

Standard-shackle locks have a metal body and solid shackle, so they're stronger and hold up better against break-in attempts than the flexible-shackle padlocks. Aluminum body locks are smaller and less likely to snag than those with zinc bodies. They have an indicator that changes from green to red to alert you if the lock was opened. Zinc body locks have a larger shackle clearance.

Flexible-shackle locks maneuver through multiple points or bend around corners, so you don't need multiple locks. However, the cable is thinner than a rigid shackle, making it easier to cut. 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.

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.

Clip these padlocks to small hasps and cables—just push the latch open and hook them through. You only need one hand to operate the latch, unlike typical padlocks. However, they have a smaller shackle clearance that limits what they can fit around. They come in a variety of bold colors that can be used to color-code locked equipment. Set your own combination and change it at any time.

To set or change your combination, insert a pointed object, such as a pencil tip or paper clip, into the keyhole on the side until it clicks. Use the rolling digits to enter your combination and push the latch closed to set it.

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. Those with an octagonal shackle are harder to cut than those with a round shackle.

Hardened-steel-body locks are the least corrosion resistant but are the strongest. They have an epoxy coating that protects them from corrosion. The coating also prevents them from scuffing nearby surfaces. 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. Stainless-steel-body locks resist corrosion better than hardened-steel-body locks. They're also stronger than brass-body and zinc-body locks. Brass-body locks are the most corrosion resistant.

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. Stainless steel shackles resist corrosion better than hardened steel. Boron carbide shackles are the hardest and most cut-resistant shackle material. They also resist corrosion better than hardened steel shackles.

Style B padlocks have a plastic cover to protect the rolling digits from freezing, corroding, or jamming caused by rain and debris.

Designed to resist corrosion from rain and snow, these padlocks operate smoothly outdoors. They unlock with a combination that you can easily set and reset.

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 brass body resist corrosion the best. Those that are chrome-plated have an added layer that strengthens the lock body.

Locks with an epoxy-coated hardened-steel body are stronger than brass and zinc body locks, so they'll hold up better against attempts to force them open. The coating adds protection from corrosion and prevents damage to nearby surfaces.

Locks with an epoxy-coated zinc body are more corrosion resistant than hardened steel locks. The coating adds protection from corrosion and prevents damage to nearby surfaces.

Hardened-steel shackles are stronger than stainless steel shackles. Those that are chrome-plated have an added layer of protection and strength. Stainless steel shackles resist corrosion better than hardened steel shackles.

Shoulders cover most of the shackle, making it difficult to access and cut. These padlocks resist corrosion for outdoor use. Set your own combination and change it at any time.

Brass-body locks are more corrosion resistant than hardened steel-body locks. They also have a boron carbide shackle, which is harder and more corrosion resistant than a hardened steel shackle.

Hardened steel-body locks are stronger than brass-body locks and epoxy coated to provide corrosion resistance.

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.

No more lost keys or forgotten combinations—these padlocks open with your Bluetooth-enabled smartphone. Each padlock has a code for registering the lock with a free app to control it via Bluetooth. In addition to locking and unlocking the padlock, you can permanently or temporarily share access to the padlock with others, monitor when and who had access to the padlock, and receive tamper alerts. Padlocks are battery operated. If your phone is not available, you can also open the padlock using a combination on the padlock keypad.

No more misplaced keys—these resettable cable locks open with a combination. Use them to secure tools, gates, and irregularly shaped objects. The cable has a weather-resistant vinyl coating that protects equipment from scratches. You can set your own combination and change it any time.
