Two stars withdrawal because there is some modification were necessary:
The top consists of two converging tubes which are bolted together. Each has two pre-drilled holes, which - as far as the design planning - flush. One thing is for screwing the other for the snap hook or spring for the object to attach.
Unfortunately, the holes are not aligned, is a flush can be as good as anything by the other by stuck (at least not carbine), so I had to correct accordingly with a metal drill.
In addition, the protective lacquer, especially at the plug connections, not carefully applied. I have therefore all connections and fittings coated with metal protective lacquer, since that will stand outside the frame until the winter.
Overall, the framework is very stable and does the job. The stated 140 Kg tensile I trust him without further notice. As comparable racks cost many times, I can highly recommend it despite the small shortcomings.
