Review on 🔌 One-Cord Cable Concealer - 157in Cord Cover, PVC Cable Hider for Home or Office - Paintable Wire Channel to Hide Power Cord, Speaker Wire, or TV Cables - 10x L15.7in, W0.59in, H0.4in - CC03 Black by Douglas Coronado

I have gray walls and this one fits perfectly. I used it to run an extension along the top of the baseboard to the lamp. People aren't kidding when they say it sticks! Make sure you get it right the first time because there are no second chances. I didn't use any connectors except for the elbow in the corner as you can't see where they connect unless you look very closely. The connectors actually made it more noticeable so I just dropped them and it looks pretty organic.
