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 an aluminum shackle have an FDA-approved lubricant, so you can use them in food production facilities. They also have a compact body that fits into tight spaces, such as inside electrical cabinets. Locks with a boron alloy shackle have the hardest and most cut-resistant shackle material. Key-retaining locks don’t let you remove the key from the lock until you close the shackle. This helps you properly secure locks before walking away with the key, reducing risk in lockout applications.

Style B locks have a steel body, so they are stronger than locks with an aluminum body. To prevent breaking from prying, shimming, or tapping, they are dual dead locking, so both ends of the shackle lock inside the padlock body. The hardened steel shackle is stronger than an aluminum shackle. A bumper around their body protects sensitive surfaces from damage if the lock knocks against them.
