A:AnswerIn order to get my 65in tv to swivel 45 degrees which is needed for the corner. I used the BXF230-G1 and used lag bolts to place a 2x4 against the wall. Then attached the mount to the 2x4. If you use a 4x4 the 75in may turn 45 degrees. Or you could add 2x6s until you are far enough from the wall. After installing I placed my entire body weight 210lbs on the bxf230-g1 before installing the tv. No manufacture will tell you to do it this way.
