American Lock A5531KA-42684 Keyed Alike Padlock

Product Description

The AMERICAN LOCK A5531KA-42684 is a keyed-alike padlock built for industrial and commercial security applications. The body is constructed from brass and steel, measuring 1-1/2 inches wide and 3/4 inches thick, with a rectangular profile. The shackle is boron alloy — a hardened material that resists cutting and sawing — and measures 1/4 inch in diameter with a 3/4-inch width and 1-1/2-inch height clearance. A 5-pin cylinder provides pick resistance. Locksmiths, facilities maintenance crews, and trade professionals install this lock wherever keyed-alike master-keying is required across multiple access points.

This padlock is well suited for securing equipment panels, electrical disconnects, gas shutoff stations, HVAC roof curb access hatches, tool cribs, and storage enclosures in both residential and light commercial settings. The keyed-alike configuration means multiple locks in a set operate on the same key, simplifying key management for service technicians who need access to several secured points during a single service call. The compact 1-1/2-inch body fits standard hasp hardware commonly found on utility and mechanical room doors.

Installation Notes

Install by a qualified facilities technician, locksmith, or licensed electrician when used on electrical disconnect lockout applications. Ensure the hasp or locking staple opening is sized to accept the 1/4-inch shackle diameter before installation. When used for lockout/tagout (LOTO) procedures, follow OSHA 29 CFR 1910.147 energy control requirements. Do not force the shackle into an undersized hasp, as this can damage the locking mechanism.
