ABSTRACT:
This invention provides an adjustable shelf device in which shelves are provided with notches defined by intersecting edges at their corners, and with elements extending across the notches to cooperate with the edges in defining openings. Extending through each of the openings is a support post being in the form of a structural angle, with its outer surfaces engaging the edges of the notch. A releasable friction member is in the opening for locking the support post and the shelf member together.
