American Lock A5561KA-43866 Keyed Alike Padlock

Product Description

The AMERICAN LOCK A5561KA-43866 is a keyed-alike padlock built for industrial and commercial access control applications where multiple locks must operate on a single key. The body is constructed from brass and steel, measuring 1-3/4 inches wide and 3/4 inches thick, with a rectangular profile suited for hasps, chains, and lockout-tagout fixtures. The shackle is boron alloy, offering significant cut resistance, and measures 5/16 inches in diameter with a 3/4-inch width and 2-inch height clearance. A 5-pin tumbler cylinder provides solid pick resistance. Locksmiths, facilities managers, safety coordinators, and licensed contractors typically specify this lock for controlled-access and LOTO compliance setups.

This padlock is appropriate for both indoor and outdoor use in light industrial, commercial, and utility environments. The keyed-alike configuration makes it practical for gate chains, equipment cabinets, valve lockouts, and electrical disconnect lockouts where a single key must service multiple points. The brass steel body resists corrosion in moderately exposed conditions. Facilities maintenance crews and safety officers commonly deploy keyed-alike sets across multiple access points to reduce key management complexity on job sites and in plant environments.

Installation Notes

Installation requires no tools beyond proper hasp or lockout device selection matched to the 5/16-inch shackle diameter. Before applying this lock to electrical or energy-isolation points, follow applicable OSHA LOTO procedures (29 CFR 1910.147) and verify all energy sources are de-energized. Do not force the shackle into an undersized hasp opening, as this can damage the locking mechanism. Keyed-alike sets should be documented and key copies controlled according to site security policy.
