I was looking for because I'm a little super freak (like when there is a half milimetre of plumb, I see it), and I found! it is a very good support, I have a lcd 116 cms 30 kgs. has fastening the moving part is centered on the 4 nuts you see in the middle (very reliable): suddenly, once attached to the wall, it is possible to adjust horizontality millimeter closer, we pours everything and it's really great. it is set in brick with good ankles cleats. The icing on the cake was delivered faster than the time originally planned. I definitely recommend.
