Dual Box

Dual Box is the evolution of Box Tunnel. It represents the perfect solution to cover two cars and protect them from bad weather conditions (rain, hail).

Like the Box Tunnel, it can be closed in a few seconds by reducing its obstruction to a few centimetres. For this reason, it is the right choice for those who have limited space and would like to exploit it to the fullest.

Suggested for

The Dual Box is ideal for covering two cars placed side by side. However, it fits with many other uses despite its primary function.

The exceptional width (up to 6 meters) grants an excellent cover for cars of any size. Whatsmore, you can also use it as storage for equipment and machinery as well as a connecting tunnel.
