American Lock is a historic U.S. padlock brand widely recognized for industrial‑grade padlocks built to withstand harsh environments and physical attack. The brand’s product focus traditionally includes solid‑body and high‑security padlocks, color‑coded aluminum safety lockout padlocks, shrouded shackle designs and specialty hasps and accessories for commercial and industrial users. Master Lock acquired the American Lock business in 2003; since then the brand has been maintained as part of The Master Lock Company portfolio while continuing to serve institutional, OEM and professional specifier markets.
American Lock products are specified across maintenance, facility management, utilities, manufacturing and contractor applications, including lockout/tagout on electrical and mechanical systems, industrial gates and storage, municipal and transportation assets exposed to weather, and OEM installations where durable padlocks are required.
Key attributes to verify when specifying or replacing American Lock models include the stamped model number, body material and finish, shackle diameter and vertical/horizontal clearance, cylinder type and keying configuration (keyed‑different, keyed‑alike or master keyed), and any color coding used for LOTO programs.
Match critical dimensions first, confirm keying and master‑key requirements, specify anodized colors for LOTO consistency, request datasheets and packing lists, and use Safsale’s images and Q&A to confirm final part numbers prior to purchase.
Note on distribution: Safsale provides product listings and sourcing support but does not assert authorized distributor status. Buyers requesting manufacturer authorization or certified warranty documentation should obtain those directly from the manufacturer or an authorized wholesaler.
