DN32 searched, found, get DN20 ...

Looking for DN32 Flexrohr me this article was delivered as a result and I scanned the item description due to the low price and the ordered items. When unpacking then the surprise, it is DN20 flex pipe. I have to move 2x Cat-7, 2x 2,5qmm Audio and 1x 7mm coax, I put three parallel lines in the ceiling. Trying to collect 2x Cat-7 ended the second cable so that it stuck about 60 cm before the end and can not move a millimeter more.

For a single cable to 10mm Flex tube is suitable for two or three conduits, a larger diameter is needed. Unfortunately I let myself be fooled by the search and bought this flex pipe.
