Abstract: A structure for supporting a product label in connection with a product rack comprised of tubular support members. The present invention provides a planar face which is configured to fit between and among the tubular members which form the rack. This generally rectangular face is used as a backing for labels, such as product labels. The present invention also discloses side walls which extend generally downwardly over a generally concave curve from the rectangular face. The curve of the generally downwardly extending side walls is such that it can snappingly engage the tubular members of the rack. In certain rectangular, square and other similar configurations of the planar face, additional downwardly extending side walls may also be included within the structure. These side walls may or may not engage the tubular members of the rack. A lip structure extending generally perpendicularly outwardly from the lower edges of the side walls is also provided.
