Steel Laminated Padlock
The Master Lock M15KALF is a steel laminated padlock designed for lockout and tagout procedures and general security tasks. Its 5-pin cylinder and boron shackle provide high-security resistance against picking and cutting. The keyed-alike configuration allows one key to operate multiple units, simplifying key management for teams. This lock suits maintenance crews and facility managers who need reliable physical access control.
Keyed-Alike Upgrade
Replacing mixed-key padlocks with this keyed-alike set removes the need to carry separate keys for every lock point. The jump is worth it when a single authorised person must secure several energy-isolation points during a shift. Boron shackle material upgrades standard steel shackles by adding greater cut resistance. No control key registration is required, so deployment is immediate.
Laminated Body Limits
The laminated steel body resists physical attack but is not weather resistant, so prolonged outdoor exposure may cause corrosion. The 7/16 inch shackle diameter limits the hasp or chain link size that can be used. A fixed keyway and non-interchangeable core mean the lock cannot be re-keyed if a key is lost. The 1 1/2 inch shackle height restricts clearance around thick bars.
