Property unfortunately have to wait a bit on the hanger but that was apparently a Priblem of Hermes. I wife have had no problems the trailer alone assemble together. Yes, the top crossbar is however already measured some generous to cope with some good effort. As I read that the Soff I stretched a bit in front of the pull of the zipper slightly stretched the fabric of the insect screen and after that it was absolutely no problem to close. I have the trailer rebuilt something because it is intended for both our Mopsmischlinge for longer trips through Holland. We have already tried it and it rolls well and certainly in the corners, which is not the case with dog trailer in this price range. Another advantage is that the trailer is not that typical rubber smell has. All in all a great part. If you want more must pay more !!!!
