This was a lifesaver. After buying a house, I discovered a huge mess of audio cables wired throughout the place, and this plate made it possible to finally get everything organized. Quality is decent, not the best, but good for the value. Super easy to use and connect even old wires to it from the back.

These wall plates look good and work well

Style: 2-Speaker

I used these wall plates for my home theater system. They are easy to install, look good, and accepted my banana plugs perfectly. They make my installation look tidy and I am pleased with the outcome. I have used other Cable Matters products in past and have always been happy with the results.
