Abstract: A merchandising shelf unit is provided that when fully expanded is about 30? wide by about 44¾? high. The width can be adjusted to compress down to about 18?. It is designed so that another unit can be stacked on top of each other using stacking pins to secure the two units. Adjustable shelves allow for different heights, within the unit, depending on products being displayed. An optional light accessory system that can be secured underneath the shelves will allow for enhanced product presentation. The merchandising shelf unit is fully attachable to a counter, as well as being portable, and the merchandising shelf unit is made of a welded steel frame, acrylic sides and doors, and injection molded clear shelves. An adjustable front door panel can be installed to close in the merchandising shelf unit and can be secured with the installation of a lockset. This door unit can be hid away in the space between the acrylic side panels and welded steel frame.
