American Lock A5531 Padlock 1-1/2 in Keyed Different

Product Description

The AMERICAN LOCK A5531 is a keyed-different padlock built for industrial and commercial security applications where a unique key per lock is required. The rectangular body measures 1-1/2 inches wide and 3/4 inches thick, constructed from brass and steel for corrosion resistance and lasting durability. The boron alloy shackle measures 1/4 inch in diameter, 3/4 inch in width, and 1-1/2 inches in height, offering cut resistance suited to high-security environments. A 5-pin cylinder provides additional pick resistance. Electricians, HVAC technicians, plumbers, and facility maintenance personnel install this padlock for lockout/tagout (LOTO) compliance and general access control.

The A5531 is appropriate for use in residential, commercial, and light industrial settings wherever a keyed-different configuration is specified. Typical applications include LOTO programs on electrical panels, mechanical equipment, gas shutoffs, and HVAC disconnect switches. Because each lock ships keyed differently from all others in a set, it is well suited for multi-point lockout procedures where individual technicians require separate key control. Single-unit packaging makes it easy to add individual locks to an existing program without purchasing in bulk.

Installation Notes

Installation of this padlock requires no tools beyond threading the shackle through a hasp or similar anchor point. Always de-energize and isolate equipment before applying a lockout padlock, following OSHA 29 CFR 1910.147 lockout/tagout procedures. Each lock should be assigned to a single authorized user and never shared. Inspect the shackle and body for wear or damage before each use in safety-critical lockout applications.
