Review on 🧱 Impressive ICC Blank Wall Mount Patch Panel: 12 Port Zero-U HD Style (IC107BP12V) by Lancy Rakesh

The distance between the keystone bushings is slightly offset. Works with nothing but sound quality connections. It's also entirely plastic, so it's constantly clicking on the supports. It would probably be worth just using a 1U frame and a 24-port keystone planet, but there really isn't room. If you don't need mixed ports, just buy a 12-port header panel.
