Abstract: A modular pallet system is provided for storing and displaying merchandise and other items. The modular pallet system uses a pallet as its support base. The pallet has at least one socket for receiving an upright to support stretchers that are adjustable to different heights along the upright. The stretchers may join multiple pallets and support shelving in a variety of configurations. Shelves or other retail fixtures may be supported by the stretchers or the upright for multiple tiers and may run between pallets. The modular pallet system offers greater versatility and customization, as compared to previously known systems.
