Already have a Modul-Air and you now want to extend? Changed your Caravan and you need to re-configure your Modul-Air?
These extension units are suitable for use with the original version of Modul-Air and allow you to extend to the appropriate size. They are suitable to fit to all Base Units with the product codes BB15, BB16 and BB17. (This code can be found on the label sewn to the inside of the roof of your Base Unit.)
Check the size of your Caravan on our size finder guide, click on any extension on this page and look at the PDF to see which units you would require. Then simply click on the required extensions to order.
