Two main roofs, connected by a Duo intermediate tarpaulin, create more space for even more possibilities. As with the Single version, end panels can be installed on both sides. The arches of the end panels, as well as the Duo intermediate tarpaulin, can be individually designed – open, closed with a white closing panel, or with a window. Each closing tarp features a zip door; in some areas, double-leaf glass-aluminium doors can be installed. By adding further Duo intermediate tarpaulins, it is possible to create an ultimately unlimited Duo Line.
