Since the gentlemen at Digitec are often completely blind, I would be interested to know which table clamp is included in the set.....anyone with eyes will notice that the fixed, non-adjustable table clamp in pictures 1 and 2 is not the same product as the fully adjustable table clamp in picture 8.... For me this is relevant because under my table top along the edge a 4 cant steel tube is installed.... The clamp on picture 1 and 2 would not fit, the one on picture 8 where you can also adjust the mounting brackets forwards and backwards would work......It is really puzzling that you as a supplier do not see that you have a wrong product in the photos....Why don't you open your eyes!
