Review on 🔌 Delamu Cord Hider Cover Wall: 157in Cable Concealer Raceway for Wall Mounted TVs - Paintable Wire Covers with Cable Management System - CC03 by Ben Boulanger

So that's pretty much what is advertised. This is a small groove to hide a cable or maybe two. I use it to hide the USB cable that powers the baby monitor. It's so small it's hardly noticeable even before the paint applied it to the greenish-yellow wall next to the white trim, but it cleaned up the wires. Note that this is not flimsy plastic - you'll need something heavier than scissors to cut it to size. The Dremel with the cutting wheel worked great. A folding saw or even a utility saw might also work, but it's definitely quite thick and I couldn't fit universal scissors through it without damaging it. Otherwise there is not much. Cut a strip of the included double-sided adhesive (I used a little on each side), stick it to the back and press into place. Use the supplied elbows and connectors to follow the fairing to the outlet. The only annoying thing is how difficult it is to remove the backing from the included adhesive without completely removing it from the track. It's more like a gel and the red tape is a bit difficult to peel off. I ended up using a small knife to peel off the backing - once you've peeled it 1/4" it's pretty easy to peel without ripping it off the backing of the raceway.
