Power and signal cables should be separated. This cable tray allows that as a wire close to the shelf allows the large IEC connectors I use to fit and keep the cable away from the audio signal cables. Cables should not be bundled together either (making a bit of a mess). This cable tray meets many of my audio cable routing needs including supporting the cables. I taped the unit in place, drilled the holes and inserted screws I had.(The shelf I mounted these cable trays to are 2 inches thick in case you're wondering.) I'm satisfied with this product.
