Truma Roof Thickness Adapter for Truma Aventa Air Conditioner Part #: 40091-16900This part is not required for installation of a Truma Aventa Comfort or Compact but is highly recommended. The roof thickness adapter is specially designed to pair with the bottom of the Truma Aventa Comfort or Compact airconditioner. As some roofs of caravans are uneven or have corrugations, the thickness adapter gives you a 100% seal every time (when installed correctly) making sure you have no water, dust or air getting in.
