    Weather-Resistant Choose-a-Color Lockout Padlocks

    Image of Product. Front orientation. Contains Inset. Padlocks. Weather-Resistant Choose-a-Color Lockout Padlocks, Style B.

    Style B

    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. 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.

    Each lock opens with a different key. All have random key numbers.
    Plastic-Covered Steel Body with Boron Carbide Shackle—With a steel body, these locks are stronger than brass locks. Their shackle is made of a boron alloy—the hardest, most cut-resistant shackle material we offer. A plastic cover shields them from water and debris.
    Plastic Keyhole Cover—Shield the keyhole from water and debris so the cylinder won't freeze, jam, or corrode.
    Pin Tumbler—Harder to pick than warded and disc-tumbler locking mechanisms.
