Extra-Clearance Choose-a-Color Keyed Alike Lockout Padlocks

With an extra-long shackle, these padlocks can secure equipment locked out by oversized hasps, chains, and other devices. They come in a variety of eye-catching colors. To help you follow lockout identification practices, you can assign colors to individuals or functions. For example, use blue for plumbing and red for electrical. Use these padlocks with a lockout device to comply with OSHA 29 CFR 1910.147 standards for safe lockouts.
They have a pin-tumbler key locking mechanism—the hardest type to pick. Choose these padlocks 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 padlocks are stronger than aluminum-body padlocks. They have a bumper around the body so they don’t scratch surfaces.
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 padlock body.
