Perfect Box, difficult Adapter Search

I am absolutely satisfied with the box. With the included universal clamps the box can be super fast and reliably attach to most standard roof racks. Unfortunately I needed for my sloping original Ford Galaxy Roof Rails Thule special 20mm-groove adapters that were to get anywhere in a hurry. Since it would be helpful if the provider of the box offer adapters with the same or at least could indicate it. As a buyer of Thule roof boxes you should inform yourself beforehand about the need for adapter systems for their own vehicle.
