The wood is not cut perfectly and you need to do some adjusting to get things lined up. Be sure to line up the interior boards in the frame as they do not go wide enough to go into both channels so you screw in the cross beam to hold it all in the center. Mounting sucks as they did not space the holes to match the studs of a door so you use the cheap plastic anchors and the door rail does slide down a bit so mount it about 1/2 inch higher than the directions state.
