Hey Andy, hey Ziggy, hey all,
@Dr-Al had the cable attached from the ceiling at that moment which I find a fast and quick solution.
One youtube link that I posted in the same thread has been clicked many times, it shows a simple solution if you find drag chains too complicated.
Note that for the cable it is better to be bent on different parts over its entire length (like in the drag chain) than always on the same part (as shown in the video).
