A:Answer The Sanus mount has built in adjustment screw on both the left and right brackets. The kit comes with a 14" long hex wrench so it is easy to get on a ladder, get above the TV, put the hex wrench into the adjusting screw and adjust left or right bracket until it is level. I also found that this adjustment came in handy when I mounted a sound bar under the TV. After putting the sound bar under the TV I was able to lower the TV using the long hex wrench in the adjustment screws, so that there was no space between the two, for a very sleek, custom look. So even if you don't place the wall bracket on the wall so it is level, you can come back and level the TV using this neat feature.
