This Expandable Two-Tier Shore Rack in Chrome is made from heavy duty chromed steel. A key feature of this rack is that it is expandable from 24" in width to 46" in width. From a shoe storage standpoint, that means it will hold from 6 pair to 12 pair of shoes. The rack has a built in locking bar that prevents over expansion of the rack. Another feature of this shoe rack is that it is stackable when combined with a second unit of same style. This rack is a great organizational space saver for shoe organization.
