Without assembly instructions, it is not so simple, until you get behind it, (not optimal accuracy of fit) to loosen to force the adapter to the extension on the stand tube and some screws, so you can set it up. The aluminum tubes should be deburred to avoid injury. If you have done that, the part is stable, and is connect build quickly. The delivery was delayed due to incorrect addressing initially by the supplier OWL SAT. The packaging was poor and the lack of invoice I had to complain. The response to my complaints was extremely fast. It would be better, of course, if they had not even been necessary.
