Continuous horizontal channels are vertically spaced every 1". Channel design allows shelves or bins to be hung in a variety of positions.
The wall panel may be directly mounted to a wall by using a set of top and bottom retainers (The Shelf, retainers and bins are sold separately). The wall panel fits under the lips of the retainers.
The retainers are cut the width of the panel and are furnished without holes making installation simple and fast, no trying to line up pre-existing holes.
