The flat parts ("clips") that you attach to the TV could have more holes and should have been longer. I would have preferred to mount the bar about 1" closer (it's 2" lower) to the bottom of my 55" TV, but the brackets didn't have enough holes to do that. / The arms weren't long enough to reach the second set of mounting screws at the top, which would keep them perfectly straight. Ironically, their instruction photos show this, so they know the flat pieces/bars are too short. I used cable ties. to attach the top of these brackets to the rods that hold the bracket that attaches to the wall mount unit. Hopefully the zippers will help keep everything straight and straight. instead of two zip ties a nut would have helped, but still better than the wall mount Sonos sells.
