When selecting the position of the holder on the wall, however, you should before the drilling of three large holes make some thoughts otherwise is quickly "ruined" the wall. As the two arms holding the carriers are not the same length, you have a minimum distance from the wall so that the meet position of the holder on the wall and just behind the center of the television remains.
Going closer than about 30cm to the wall, "travels" the TV due to the different lengths of metal arms left or right away and the holder is no longer centered behind the TV.
This you should definitely keep in mind before hanging, then nothing can go wrong. Just earlier measure exactly where the holder has on the wall and how far the TV to hang from the holder.
The settings are very diverse.
Strong buy recommendation!
