Master Lock 5KALJ-A376 Keyed Alike Padlock 2 Inch

Product Description

The MASTER LOCK 5KALJ-A376 is a laminated steel padlock designed for maximum-security applications in commercial, industrial, and trade settings. The body measures 2 inches wide and is constructed from layered laminated steel for high resistance to cutting and prying. The shackle is made from boron alloy steel, measuring 3/8 inch in diameter, 15/16 inch in width, and 2-1/2 inches in height. The keyed-alike configuration allows multiple locks to operate on the same key, making it a practical choice for job sites, equipment rooms, and facility lockouts where a single key must open several locks. Licensed tradespeople and facility maintenance professionals are the primary installers.

This padlock is suited for securing electrical panels, HVAC equipment enclosures, utility access points, valve lockout stations, and storage areas in both residential and commercial environments. The keyed-alike feature is particularly useful in lockout/tagout (LOTO) programs where technicians need consistent key control across multiple lock points. The 4-pin tumbler cylinder provides solid pick resistance for general industrial use.

Installation Notes

Installation requires no tools beyond fitting the shackle through the intended hasp or lockout device. Ensure the hasp slot clearance matches the 3/8 inch shackle diameter before installation.
