A two-piece, adjustable width merchandising tray for the organized display of multiple product containers. Two L-shaped tray sections, formed of plastic material. The bottom portions of the two L-shaped sections are provided with laterally extending, interengaging fingers that enable the width of the tray to be adjusted for different product sizes while maintaining substantial continuity to the surface of the bottom structure for containment of product leakage. An asymmetrical side wall arrangement with a forwardly projecting hand grip at the front of one of the side walls enables individual trays to be removed and replaced from a closely packed array of trays arranged in side-by-side fashion. The trays can be conveniently lifted and carried for product restocking, reorganizing, tray cleaning, etc. A simple pull strip and paddle arrangement enables product to be fronted at all times. Double stacking of product containers is also accommodated. Densely stacked, attractive, and efficiently serviced product displays are facilitated.
