Surprised to see the opening no manual, I quickly realized, however, the reason: the assembly is a cinch, even for someone of little "resourceful". The two tripods are arranged on the side of the cover, the transverse bars in the middle. Simply choose the desired width according to the number of crossbars to combine, edit them together by simple fitting and screw a quarter turn, and climb all on tripods. All looks good strength and has a height adjustment range and extremely satisfactory width. Only slight downside, deployment tripods can be a little "hard".
