I bought these for my sister-in-law for mounting Tv's to the wall that already had receptacles installed behind the TV. It works great if you have the TV pulled off the wall via the bracket because there is more room. On one of the Tv's the bracket kept the TV close to the wall so the profile of this unit was too deep. Might have been better if the plug in was at the bottom of this unit. This is the reason I took off one star.
