I had a really hard time finding a media and power solution that would fit on a standard gang board. This is the best I could find and it didn't let me down. I bought one with a 12 foot power cord, but other lengths may be available. Wiring to each outlet was as simple and durable as possible. The power cord protrudes up or down depending on how you align the plastic cover on the electrical connector, which may or may not be behind the media cable entry hole. The attachment of the entire socket using the screw and clip method was decent. I don't use much power as I only power the soundbar but it works great and is very durable as the electrical cord wasn't flimsy or economical.
