Abstract: This invention is directed to caddy devices mountable on non-porous surfaces by means of suction cups which are easily repositioned in all directions. The devices are characterized by streamlined frame portions, support elements for slidably receiving suction cups and recessed covers that conceal the mounting apparatus from plain view. The disclosed configurations insure close attachment of the caddy device to the mounting surface. Stabilizing structures are also provided for the caddy frame. In various illustrated embodiments, the caddy can be a towel ring, toilet tissue holder, storage rack or multipurpose organizer.
