Hello together, who can tell us how to attach an awning to the groin/multirail (planned for an awning) with an opening of 10mm (no pure keder bar in the classical sense) on the Nissan Primastar Seaside? We have no awning, but occasionally want to attach a roof tent. Furthermore, we find nowhere a type designation of these two bars, which are located on the car to the right and left. (e.g. the VW has a so-called C-bar and also no pure keder bar). Sel bst, when like a well-known tent manufacturer had written to us and the data of our bar of the Nissan Primastar Seaside had been transmitted, could not help us and so could/wanted to sell us so unfortunately no tent, as the tents would slide out of the bar (because of the 10mm opening). Are there any adapters, which someone already uses to attach to it then an awning? I am curious!
