Tested to withstand the toughest break-in methods, these padlocks keep storage containers, gates, and other outdoor equipment safe when you aren’t around. They fit around oversized hasps or large chains thanks to their extra-long shackle. They’re rated UL 437 or EN 12320 to prevent access from lockpicking, hammering, cutting, and more. An internal plate blocks drill bits from penetrating the cylinder. They’re made from materials that resist corrosion caused by rain and snow. Choose keyed differently locks if you need locks that each open with a different key.

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.

Brass-body locks resist corrosion better than stainless steel-body and hardened steel-body locks. Hardened-steel-body locks are stronger than brass-body and stainless steel-body locks. Locks with a chrome-plated body have added strength and an extra layer of protection against corrosion.

Chrome-plated boron carbide shackles are the hardest and most cut-resistant shackle material. They’re plated for added strength and an extra layer of protection against corrosion.

Padlocks with a keyhole cover keep out water and debris to protect the cylinder from freezing, corroding, and jamming. They have a tethered cap for an extra-tight seal.

Disc-tumbler key locking mechanisms are harder to pick than basic warded locking mechanisms.

EN 12320 designates levels of security for padlocks on a scale of 1 to 6. The higher the rating, the harder it is and the longer it takes to break into or damage the padlock.

Raised shoulders cover most of the shackle on these padlocks, making it difficult to access and cut. More secure than standard padlocks, these are often used on unmanned access gates and other areas where added security is needed. Choose them if you need several locks that open with the same key. If the lock or key with the key number you want isn’t listed, order the "Other Key Numbers" and specify your desired key number.

Style B padlocks have a steel body, so they’re stronger and withstand physical attacks better than locks with a brass body. All are chrome plated for extra strength and corrosion resistance. Those with a chrome-plated hardened steel body are even stronger. They also have a free-spinning plate within the key cylinder, which spins continuously to prevent a drill bit from penetrating the cylinder. Their boron carbide shackle is tougher to cut and resists corrosion better than a hardened steel shackle.

Secure items with large hasps or thick chains outdoors. These padlocks have a longer shackle than typical padlocks. Use them around your facility, both indoors and out, to prevent theft and unauthorized access. All have a pin-tumbler key locking mechanism, which is the most difficult locking mechanism to pick. The more pins a lock has, the harder it is to pick.

Choose these locks if you need several locks that open with the same key. If the lock or key with the key number you want isn’t listed, order the "Other Key Numbers" and specify your desired key number.

Steel-body locks are strong, and they’re less likely to deform from break-in attempts than brass-body locks.

Locks with a cover have extra protection against weather and impact. They’re a reliable choice for securing equipment, such as valves, in harsh outdoor environments. Boron carbide shackles are tougher to cut than hardened steel, brass, and stainless steel shackles. The chrome plating gives them extra strength and a layer that protects them from corrosion.

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 body. Those with an octagonal shackle are harder to cut than locks with a typical round shackle.

Style C and D locks have a bumper around the body, so they won’t scratch nearby surfaces.

Rain and snow are no problem for these corrosion-resistant padlocks. Use them around your facility, both indoors and out, to prevent theft and unauthorized access. All have a pin-tumbler key locking mechanism, which is the most difficult locking mechanism to pick. The more pins a lock has, the harder it is to pick.

Choose these locks if you need several locks that open with the same key. If the lock or key with the key number you want isn’t listed, order the "Other Key Numbers" and specify your desired key number.

Steel-body locks are strong, and they’re less likely to deform from break-in attempts than brass-body locks. All have a stainless steel or plastic cover that protects against weather and impact. This makes them a good choice when you need to secure equipment, such as valves, in harsh outdoor environments. Boron carbide shackles are tougher to cut than hardened steel, brass, and stainless steel shackles. The chrome plating gives them extra strength and a layer that protects them from corrosion.

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 body. Those with an octagonal shackle are harder to cut than locks with a typical round shackle.

Style A locks have a bumper around the body, so they won’t scratch nearby surfaces.

Made from corrosion-resistant materials, these padlocks lock out equipment outdoors and come in a variety of bold colors that stand out from regular padlocks. The body of these locks is enclosed in a plastic cover to protect against physical damage and corrosion. To adhere to lockout identification practices, assign colors to individuals or functions, such as blue for plumbing and red for electrical. Use them with a hasp, chain, or another lockout device to comply with OSHA 29 CFR 1910.147 standards for safe lockouts.

Choose these padlocks if you need several locks that open with the same key. They have a pin-tumbler key locking mechanism, which is the most difficult locking mechanism to pick. The more pins a lock has, the harder it is to force open.

Steel-body locks are stronger and hold up better against break-in attempts than brass-body locks. Their shackle is boron carbide—the hardest and most cut-resistant shackle material available. To protect the internal components of the lock, they have a plastic cover over the keyhole to shield against water, snow, and other debris.

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.

Brass-body locks are the most corrosion resistant.

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.
