Used on my Sony TV which is attached to a wall support! The cable will slot right in, it does not move! On the other hand, the elbow rotates 360 degrees! And so I tell them that it's convenient; I had planned to pass the cable through the bottom and finally I had to do it from the top, this mobility has saved the installation ... I highly recommend this mark, finishing the impeccable quality piece, no cut mute, or else! This is perfect!
