Secure your containers – with the Breech Base system

Flexible anchoring for precise and stable container placement – even when there’s a gap between foundation and delivery.

The steel structure is ready, the project is moving forward, and containers are ordered.
But there’s one key question left:
How do you ensure stable and accurate placement of your containers – without compromising on flexibility or safety?

That’s where the Breech Base system comes in.

What is the Breech Base system?

Breech Base is a purpose-built anchoring system that allows you to secure containers in a simple, precise, and long-lasting way – ideal for construction sites, modular buildings, offshore projects, and industrial setups.

The system consists of four components that work together:

Deck Socket DF-66 – welded to the steel structure or embedded into the foundation
Twistlock BF-66 – locks the container safely into the socket
Breech Base Cover – protects the socket when no container is in place
Spanner – used to easily remove the cover when needed

Key benefits of the Breech Base system

✅ Stability in all conditions
Containers are securely locked in place – even in strong winds, uneven ground, or vibrations.

✅ Full project flexibility
Prepare the foundation well in advance and place the container exactly when needed. Avoid costly delays or rushed adjustments.

✅ Clean and protected installation
The socket stays clean and dry with the Breech Base Cover – even during longer waiting times between installation steps.

✅ Accurate alignment – every time
No guesswork or measuring tape needed. Your container lands exactly where it should.

✅ Fast mounting and low maintenance
No special tools required. Everything fits together and can be reused when containers are relocated or replaced.
