A:AnswerI realize this question was posted over a year ago but I'm addressing it in hopes another person may have the same question. This shelf adjusts up or down via allen key. Simply remove (2) plastic covers (Front & Top) exposing the allen-head screw located in the center of the panel and adjust as desired.
Note: The adjustment will not exceed 1" inch.
A:AnswerYes the shelf is super strong ones it’s properly mounted on the wall. Just make sure wherever your mounting it that there is a wood stud on the wall.
A:AnswerThe shelf is 18 inches wide. Your sound bar is 23 inches wide. There will definitely be some overhang. It depends on you and your taste. You will have to look at it.
A:AnswerHi,
Unfortunately, It will not work to be installed in the corner. This shelf is mounted onto the wall and will not be lined up under your corner mount. If you are ok with it not being perfectly lined up under your TV it will work just fine. Please see our instruction manual below for more info.
