The AMERICAN LOCK A5570KA-42248 is a keyed-alike brass and steel padlock designed for industrial and commercial security applications. The rectangular body measures 2 inches wide and 3/4 inches thick, providing a solid, compact form factor suited for hasps, chains, and equipment lockout points. A 5-pin cylinder delivers reliable pick resistance. The boron alloy shackle resists cutting and sawing, making this lock appropriate for high-demand environments. Licensed trades and facility maintenance professionals commonly install this lock as part of lockout/tagout (LOTO) programs or perimeter security setups where multiple locks must share a single key.
This padlock fits standard hasp and chain applications in light industrial, commercial, and trade service settings. The keyed-alike configuration allows multiple A5570KA-42248 units to be operated with one key, which is a practical requirement on job sites or facilities where technicians need access to several secured points. The 3/8-inch shackle diameter and 1-1/8-inch shackle height accommodate most standard hasp slots and chain links without modification.
Designed as an OEM-style keyed-alike padlock compatible with standard hasp and chain lockout hardware used in industrial, commercial, and trade service applications.
Installation requires no tools — the shackle inserts directly into a compatible hasp or chain link. Before securing equipment, ensure all energy sources are isolated in accordance with applicable LOTO procedures and OSHA 29 CFR 1910.147 lockout/tagout standards. Inspect the shackle and body for damage before each use. Do not force a bent or damaged shackle into the lock body.
