American Lock A800 Door Hasp 8.5x4.5 in Hardened Steel

Product Description

The AMERICAN LOCK A800 is a heavy-duty door hasp constructed from hardened steel, designed to secure doors, gates, and storage enclosures with a padlock. Measuring 8.5 inches in length and 4.5 inches in width, the A800 accommodates padlock shackles up to 0.5625 inches in diameter. The hardened steel construction resists cutting and prying, making it a reliable choice for facilities, warehouses, job sites, and commercial properties where access control is a priority. Electricians, locksmiths, and facilities maintenance technicians commonly install this type of hasp as part of a lockout/tagout or physical security setup.

The A800 is suited for both residential and light commercial applications. It installs on swing doors, sliding doors, shed doors, and storage unit access points. The wide 4.5-inch plate provides a stable mounting surface and distributes force across the door surface, reducing the risk of pull-through under load. This hasp is intended for use with a compatible padlock, which is sold separately.
