A rack assembly having rotationally mounted support members is disclosed herein. Each of the three embodiments of those members allows the next lower support member to be rotated into a vertical attitude to permit the insertion into the rack of an item which is greater in height than the spacing between adjacent support members. Various means are included in each support member design for interacting with the tip of the flange of the next lower support member to selectively maintain it in vertical attitude. The interacting means discussed include an outwardly projecting medial portion on the underside of the flange, a shoulder in the normally vertical portion of the support means which interconnects the flange with the means for affixing the support member to the rack, and, where it is desirable to be able to support a string of support members in the vertical attitude, the medial portion discussed above is included with a tail piece which extends outward from the support member in opposition to the flange.
