American Lock A5571KA-27678 Keyed Alike Padlock 2in

Product Description

The AMERICAN LOCK A5571KA-27678 is a heavy-duty keyed-alike padlock built for industrial and commercial access control applications. The body is constructed from brass and steel, measuring 2 inches wide and 3/4 inches thick with a rectangular profile. The shackle is made from boron alloy for cut resistance, with a 3/8 inch diameter, 3/4 inch width, and 2 inches of shackle height for clearance. A 5-pin cylinder provides strong pick resistance. This padlock is installed by maintenance technicians, security professionals, and tradespeople managing keyed-alike master-key programs across multiple entry points.

This padlock suits commercial and industrial environments where multiple locks must operate on a single key. Typical installations include gate hasps, equipment enclosures, storage units, electrical panel cages, and job-site lockout/tagout stations. The keyed-alike configuration allows one key to operate several locks simultaneously, reducing key management burden in multi-lock installations. Its solid rectangular brass-and-steel body makes it appropriate for both indoor and moderate outdoor use.

Installation Notes

Installation is performed by maintenance or security personnel following the facility lock program. Before installing in a lockout/tagout application, verify compliance with OSHA 29 CFR 1910.147 energy control procedures. Ensure the hasp or staple opening accommodates a 3/8 inch shackle diameter and provides adequate clearance for the 2-inch shackle height. Do not force the shackle into an undersized hasp, as this may damage the locking mechanism.
