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.

Brass-body locks have excellent corrosion resistance, but they’re not as strong as steel-body locks.

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.

Hardened steel shackles are stronger than stainless steel shackles, but they don’t stand up as well to corrosion. 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.
