Lockout Padlock for Energy Isolation

The Master Lock 410KAS6BLK is a thermoplastic lockout padlock designed for industrial safety programmes. Its black body and open steel shackle provide visible identification during maintenance procedures. The keyed-alike configuration allows a single key to operate multiple locks across a facility. It suits maintenance teams needing consistent lockout compliance.

Keyed Alike Limits Key Management Flexibility

Every padlock in the set operates with the same two supplied keys, which simplifies distribution but prevents individual access control. If a key is lost, every lock in the group is compromised until replaced. Non-removable keyways mean the key cannot be withdrawn while the shackle is open. This design restricts use to scenarios where shared access is intentional.

Thermoplastic Body Resists Chemical Exposure

The lock body is moulded from chemical-resistant thermoplastic rather than metal, so it withstands solvents and cleaning agents common in process plants. Steel shackle components remain exposed to physical attack but the body will not corrode or conduct electricity. Buyers needing a fully metal body or a shrouded shackle for higher physical security cannot use this model.

Questions about this item

Is the keyed-alike set the right choice if I need every padlock in the group to open with the same key?

Yes, the 410KAS6BLK is supplied as a keyed-alike set, so a single key operates all padlocks in the pack.

What does the 13/16 in horizontal shackle clearance mean when the lock is on a hasp?

It gives 13/16 in of space between the shackle legs, allowing the lock to fit standard lockout hasps and chain links.

How does the 1/4 in steel shackle diameter affect the lock's resistance to cutting?

The 1/4 in diameter steel shackle provides a solid barrier that resists bolt-cutter attacks while fitting common lockout points.
