Well, so is the part not cheap.
But I wanted a wall mount that I can as far as possible to pull out from the wall rotate, and adjust the inclination.
The biggest "drawing zone" had at that time only this Sanus.
I used this for my recently purchased Samsung LED TV 46 ". (The 46" has been surpassed by a Samsung 55 "UE55F8090SLXZG replaced.)
Do me but still bought additional screws at the hardware store. The heavy wall bracket to hold on the wall yes bombproof. And unfortunately at my place on the wall where I unscrewed the bracket on the wall, a slight bend in the wall (which have been thinking architects in the rubbish, is beyond my knowledge!).
Due to the bend in the wall of the Sanus is attached only to the left 3/4 of the wall, the right quarter hovering a few cm away from the wall. Does not fall on.
Have secured a total of 8 screws the holders. This keeps!
When the arm is fully extended, as already overloaded even up some weight on the arm and holder.
The only drawback:
The joint in the extendable arm is pretty stiff. I then need both hands when I want to move out or retract the arm.
Turn goes perfectly, beautifully smooth. (But should be the same since my 55 "another height than my previous 46", and the upper edge) is also adjustable in height.
However, I had the holder on the TV side turn because the Samsung 55 "attachment points had on a whole different level. Have the whole construction disassembled, and reassembled upside down. Now everything fits perfectly!
