The Bulldog CT440 is a heavy-duty container lock designed to provide high-level security for shipping and storage containers. This adjustable bar works by clamping around the vertical locking handles of the container doors, preventing them from being opened even if the standard container locks are compromised.

Constructed from case-hardened steel, the unit is highly resistant to physical attacks, including sawing and drilling. It is supplied with the Bulldog Super Lock Bolt, a specialised locking mechanism engineered to be drill and pick resistant. Because the device is fully portable and requires no permanent fixings, it is an ideal choice for securing leased containers or for use across multiple sites where permanent modifications are not permitted.

The CT440 is commonly used on construction sites, in storage yards, and for goods in transit. Its adjustable nature ensures compatibility with a wide range of container types where the outside distance of the bars falls between 242mm and 467mm.

The Abloy replacement key is designed specifically for Bulldog security products that utilise the high-security Abloy cylinder. Known for its exceptional resistance to physical attack and environmental factors, the Abloy mechanism is a core component in heavy-duty security hardware. These keys are precision-cut to maintain the integrity of the lock's internal components and ensure smooth operation.

Typically used with Bulldog hitch locks, wheel clamps, and ground anchors, this key is essential for maintaining access when original keys are misplaced or when additional keys are required for fleet management or multi-user scenarios.
