Abstract: A modular compartment for displaying products therein. The modular compartment comprises in one unit a front panel, a pair of side panels which interlock with the front panel, and a back panel which interlocks with the side panels. The side panels have snap off sections for adjusting the depth of the modular compartment so as to adapt to different shelving dimensions. The side panels also have snap out connector pins for securing together adjacent modular compartments. One or more lateral dividers may be provided for separating products within each modular compartment. Also, an optional perforated peg panel may be snap fit onto the front panel so that mating peg clips and/or actual representative products may be displayed on the front of the modular compartment. Both the front panel and the optional perforated peg panel have guides formed therein for retaining product identifier strips.
