Shipping Container Locks & Security

A shipping container is only as secure as its lock. Because container doors use exposed locking bars and a standard padlock leaves its shackle open to bolt cutters, the right security hardware makes the difference between a container that deters thieves and one that invites them. Our lock range is built to remove the weak points attackers rely on.

The catalog covers layered security. Lock boxes are steel housings that shroud your padlock so cutters and pry bars cannot reach it. Heavy-duty padlocks use a disc or puck shape with a shielded shackle that resists cutting. Door bar locks clamp over the vertical locking bars so the doors cannot be opened even if the handle is reached. And twist locks secure stacked containers together during transport.

How to choose: the strongest setup uses more than one layer. Start with a lock box and a hardened puck or disc padlock, the combination that defeats the most common cutting attacks. Add a door bar lock for containers holding high-value contents or sitting in exposed, unattended locations. For a quick decision, match the hardware to your risk: remote job sites and valuable inventory warrant maximum layering, while a backyard storage container may only need a solid lock box and padlock.

Our guide on how to secure a shipping container breaks down each lock type and how to combine them for real theft prevention.
