The Closet Organizing Trouser Rack.
Extending only 16-1/2" (or 18") from a closet wall or door, this rack keeps 20 (or 10) pairs of slacks neatly hung and readily accessible. It easily mounts to a closet wall or door and has a 10-gauge steel support bracket that holds 20 hardwood dowels so you can hang trousers flush against the wall, then swing them out individually, up to 180 degrees. The 5/8"-diameter dowels reduce creasing of even fine fabrics and one-inch vertical spacing between the dowels allows for easy visibility.
Support bracket has solid hardwood back with clear lacquer finish and mounts with self-tapping drywall anchors (included).
