Product DescriptionThe AMERICAN LOCK A5400 is a heavy-duty stainless steel padlock built for demanding environments where corrosion resistance is a priority. The body and shackle are both stainless steel construction, making this lock well-suited for outdoor, marine, and chemical-exposure applications. The rectangular body measures 1.75 inches wide and 0.75 inches thick. A 5-pin tumbling mechanism provides solid pick resistance. The A5400 ships keyed different and is rekeyable, which is a practical advantage for facilities managing large lock inventories. Licensed security and facilities professionals are the primary installers, but the lock is straightforward to deploy without special tooling.The A5400 is designed for use in industrial, commercial, and heavy residential settings where exposure to moisture, salt air, or mild chemicals would degrade a standard hardened steel or brass padlock. Typical applications include gate hasps, electrical panel lockouts, storage units, and equipment enclosures. The 5.16-inch shackle diameter, 0.75-inch shackle width, and 1.125-inch shackle clearance height accommodate standard hasp slots and lockout-tagout devices commonly used in industrial facilities.Key FeaturesStainless steel body and shackle provide corrosion resistance in wet or chemically active environments1.75-inch wide rectangular body with 0.75-inch body thickness5-pin cylinder for improved pick resistanceKeyed different configuration — each lock ships with its own unique keyRekeyable design allows key changes without replacing the lock bodyShackle clearance of 1.125 inches fits standard hasps and lockout-tagout hardwareCompatibilityDesigned as a direct-fit replacement or new-installation padlock for standard hasp and staple hardware requiring a 1.75-inch body width and a shackle diameter of 0.3125 inches.Installation NotesNo special tools are required to hang this padlock on a hasp or staple.
