Master Lock 1KALJ-2729 Laminated Steel Padlock 1-3/4 in

Product Description

The MASTER LOCK 1KALJ-2729 is a laminated steel padlock designed for maximum security applications in commercial, industrial, and trade environments. The padlock body measures 1-3/4 inches wide and is constructed from layered laminated steel plates, providing high resistance to physical attack. It operates on a keyed-alike configuration, meaning multiple locks in a set can be opened with the same key — a practical advantage for facilities managers, contractors, and service technicians who manage multiple access points. The 4-pin cylinder adds an additional layer of pick resistance for demanding job-site or equipment lockout use.

This padlock is suited for securing gate hasps, tool cribs, equipment enclosures, lockout/tagout stations, and storage units across residential, commercial, and light industrial settings. Tradespeople working under OSHA lockout/tagout (LOTO) programs will find the keyed-alike feature especially useful for multi-point energy isolation procedures. The steel shackle provides durable resistance to cutting and prying in standard service conditions.

Installation Notes

Installation of this padlock requires no special tools beyond proper hasp or lock bar hardware rated for the intended security application. Before use in lockout/tagout applications, verify compliance with applicable OSHA 29 CFR 1910.147 energy control procedures. Inspect the shackle seat and hasp alignment to ensure full shackle engagement before applying load. Do not use this padlock as the sole barrier for applications requiring a listed or rated security device beyond its intended classification.
