Use the tube for the cable of my flat screens in the bedroom, as the black cable from the TV, Receiver etc. at the bright wall just disturbed. In addition, the rather long power cables were laid on the short walk to the outlet of mine together in loops and secured with wire. The thus relatively thick bundle of cables have yet perfectly fitted into the cable conduit! Have just opened a bit and the cable pushed in the tube. The subsequent installation in finished installed cables is possible without any problems. The openings of the spiral hose do not bother me, because the whole picture right and the ugly cables are completely covered. You just see a white tube and no ugly cable bundles. Simple but effective, so of me 5 stars.
