Useful for lockout identification practices, these padlocks come in a variety of colors to catch your eye. Assign a color to individual people or departments, such as blue for plumbing or red for electrical. Use them with cables and other lockout devices to keep equipment off during maintenance or repairs. This helps you comply with OSHA 29 CFR 1910.147 procedures. 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.

Style A locks have an aluminum body that resists corrosion better than locks with a steel body, but they’re not as strong. Their shackle is either aluminum or boron alloy, both of which resist corrosion better than a hardened steel shackle. Locks with a boron alloy shackle have the hardest and most cut-resistant shackle material.
