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

Product Description

The MASTER LOCK 1KALJ is a laminated steel padlock built for general security applications in trade and industrial environments. It features a reinforced laminated steel body with a double locking mechanism that resists prying, and a hardened steel alloy shackle that resists cutting. The shackle measures 5/16 inches in diameter with 2-1/2 inches of clearance, making it suited for securing hasps, chains, gates, and equipment lockouts. A proprietary rustproofing treatment extends service life in outdoor or moisture-prone environments. Licensed HVAC techs, electricians, and plumbers commonly use padlocks of this type for LOTO (lockout/tagout) compliance during equipment servicing.

The 1KALJ is intended for general security use across residential, commercial, and light industrial settings. Its compact 1-3/4 inch body and adequate shackle clearance make it a practical fit for tool storage, equipment enclosures, gate hasps, and service van storage. It is well suited to tradespeople who need reliable, corrosion-resistant lockout hardware on job sites exposed to weather or wash-down conditions.
