This invention provides an adjustable system for the storage, organization, display, promotion and dispensing of containerized goods, especially those packaged in boxes, jars, bottles and cans. The system is primarily intended for use on supermarket, convenience store and pharmacy shelves to keep products and labels organized and at the front of the shelf, both appealing and accessible to the consumer. This system is modular and changeable, and is easily rearranged to accomodate rows of products of various shapes and sizes, even within a single system unit. The benefits provided by this system may lead to increased product recognition, lower out-of-stocks and inventorying requirements, improved presentations, optimal real estate utilization, and ultimately, increased profits and sales.
