Master Lock 3KALH-0344 Laminated Steel Padlock Keyed Alike

Product Description

The MASTER LOCK 3KALH-0344 is a laminated steel padlock designed for securing equipment, panels, gates, and service access points in trade and light industrial applications. The body measures 1-9/16 inches wide and features a laminated steel construction that resists cutting and corrosion. The hardened steel shackle has a 9/32-inch diameter and provides 2 inches of shackle clearance, giving installers enough working room for hasps, chains, and lockout hardware. This padlock ships keyed alike, making it a practical choice for job sites or facilities where multiple locks must be opened with a single key.

This padlock is suited for lockout/tagout programs, equipment enclosures, tool cribs, electrical panel access, and general job site security. Electricians, HVAC technicians, plumbers, and facilities maintenance crews commonly use keyed-alike padlock sets to maintain consistent key control across multiple access points. The silver finish and laminated body construction make it appropriate for both indoor and outdoor use in moderate-exposure environments.

Installation Notes

Installation requires no tools. Confirm shackle clearance is sufficient for the hasp or chain before securing.

Do not use as the sole security device in high-security or high-theft-risk environments without supplemental hardware.
