Master Lock Co 1KALJ-2730 Laminated Padlock Keyed Alike

Product Description

The MASTER LOCK CO 1KALJ-2730 is a laminated steel padlock built for trade and commercial applications where multiple locks must operate from a single key. The body measures 1-3/4 inches wide, with a 2-1/2 inch long shackle and a 5/16 inch shackle diameter, making it suited for securing hasps, chains, gates, and equipment enclosures. Keyed alike to the 2730 keyway, this padlock accepts Master Lock key blank K1BOX or Ilco blank M1 TV 320-952, giving service technicians and facilities personnel a straightforward rekeying and key duplication path. Sold in a boxed unit of measure.

This laminated padlock is appropriate for light industrial, commercial, and residential use. Common applications include HVAC equipment lockout, electrical panel access control, gate and storage enclosure security, and job-site equipment staging. The keyed-alike configuration is particularly useful when a technician or facilities manager needs one key to open several padlocks across a site, reducing key ring complexity and improving workflow efficiency. The 2-1/2 inch shackle length provides clearance for standard hasp loops and chain links without excessive exposed shackle.
