The 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.
Designed 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.
No special tools are required to hang this padlock on a hasp or staple. Confirm hasp slot width is sufficient for the 0.3125-inch shackle diameter before installation. For lockout-tagout applications, verify the lock meets site-specific OSHA 29 CFR 1910.147 program requirements. Rekeyable cylinder service should be performed by a qualified locksmith.
