The rack is expandable and may consist of two or more horizontal bases each equipped with cap body supporting pairs of vertical members and horizontal visor support members perpendicular to the vertical members. A number of base units equipped with horizontal and vertical support members may be assembled together and held in place by associated vertical supports.
