Let's start with the fact that the box exploded during transport and the courier had to repack it, so he needs to look a little inside the box. Nevertheless, everything arrived! I'm not in favor of two long pieces being cut in half, but I understand this is done so they can be sent. The four end clips as mentioned by others don't work on all panels and I need to change mine for the panels I have. You need a second person for support. Things slip too far for one person to safely handle alone. It would be great if every bolt had a washer, especially steel bolts on aluminum parts.
