Abstract: A shelf system having a shelf and a bracket. The bracket and shelf interlock to form a snap together unit. The shelf has a channel formed along each of its lateral edges, and each channel extends from the front to the rear of the shelf. The channel is downwardly facing. A tab is lanced out of the side wall of the shelf, and positioned within the channel to form an interference means. A whole is punched in the bracket to cooperate with the tab and the webbed material between the hole and the upper edge of the bracket interferes with the tab, thereby preventing removal of the bracket from the channel after the bracket is assembled to the shelf. The side wall of the shelf is flexible to allow insertion of the bracket beyond the tab. Additionally, secondary engagement means is provided between the lower edge of each rib on the shelf and a support finger on the bracket after the brackets are inserted into the channels of the shelf, the brackets are firmly attached to the shelf.
