Review on Houseables Picture Hanger Kit - Mirror Hanging Hardware, French Cleat, 3 Pair, 6 Inch, 50 lbs Capacity - Aluminum Z Bar Clip Rail Bracket - Wall Mount Hangers with Nails - White Board Mounting, Shelf, Art by Sasha Hsiao

Contrary to the picture/graph, this is not actually a French plank and there is a gap where the two pieces meet. This will tilt the object you are hanging forward. If the gap was small, no gap, or the gap was slanted like you do with wood, then the object you are hanging will hang perfectly vertically. I think they assume that people will only use them to hang pictures and be content with the bottom border. its frame rests on the wall. Wouldn't have given such a bad review had her description been correct. I will turn back.
