Abstract: A slotted display wall provides a modified "T" shaped slot having a throat open to the front face of the panel and a vertically extending opening inwardly spaced from said throat, said opening including opposed angled walls extending in both directions from said throat to end extremities, the angled walls being angled toward the back face of the panel from said throat to the extremities, said opening also including end walls joining the extremities of the angled walls and extending to a rearward face spaced from the back face of the panel. The opening provides a relatively deep dimension adjacent to the throat and increasing material thickness between the angled walls and the front face as the angled walls extend from the throat towards their extremities. This permits conventional cantilever brackets to be installed through the slots and provide upper mounting portions which engage the angled walls at a point substantially spaced from the throat where greater material thickness exists.
