Abstract: A merchandise display system for supporting products in a retail environment in a vertical array, the system having channeled slatwall with a plurality of horizontal, vertically adjacent generally P-shaped channels upon which different types of hardware and bracketry can be engaged. The P-shaped channels have upper and lower troughs in which different types of hooks and brackets are insertable, with the sections of the channels as load bearing surfaces. The slatwall can be formed with at least two channels extending from a single contiguous rear wall. The rear wall of the slatwall is securable to a backer panel with corrugations which are orthogonal to the channels. The slatwall is fastened to one or more backer panels by lances which protrude from the backer panel, and/or by securement fasteners between the channels of the slatwall.
