The basic doors are also available in the folding version Doubl. This handy opening system allows the door to bow to book thanks to the leaf cutting. The cut, in Doubl asymmetric version and divides the panel in a proportion of 1/3 and 2/3. The door, once opened, occupies part of the free space of passage but has the advantage of not clutter inside the room. Such an ideal solution in all those situations where you have available reduced environments.
