Somewhere out in cyberland is a person who reviewed this product and said that the original hardware did not hold and she lost all her stemware. Her tale of woe was appreciated because I was able to modify how I hung these to ensure the safety of my wine glasses. I screwed a 70 inch 1X2 wood furring strip into the wall studs of my dining room (4 screws total) then screwed the racks into furring strip with cabinet screws. I also modified picture hangers to cant the racks up slightly so that my glasses would never slip off because some of the dowels aren't perfectly straight. With this modifications, the racks are strong and lovely.
