Abstract: Channels and panels for walls and other surfaces, for use in applications such as retail display. The panels feature slots and channels within the slots. The channels in turn support brackets and other fixtures which may be used to suspend materials from the wall or surface. Channels of the present invention, unlike conventional channels, have no back surface, when viewed in cross section, but instead feature closed front faces. A first embodiment of such channels features flanges with rounded extremities, a closed face similar in appearance to conventional vertical slotted channels, and a structure which reduces the amount of material required. A second embodiment of such channels features an open back structure and flange protrusions to increase the load bearing capacity of the channels.
