Abstract: A partition panel system including a partition frame with vertically spaced horizontal frame members defining first discrete attachment locations, a pair of horizontally spaced blades adjustably attached to selected ones of the first discrete attachment locations, the blades including opposing inner surfaces defining vertically spaced second discrete attachment locations, and shelves adjustably attached to selected ones of the second discrete attachment locations. This allows the shelves to be horizontally and vertically adjustably supported on the partition frame in a selected one of a variety of positions. At least one shelf has a front portion with edges that extend partially around in front of the blades, thus providing increased surface area. The shelves are supported on the blades by shelf supports. Connectors on the ends of the shelves are movable between engaged and disengaged positions for securely engaging the shelf supports.
