Short Expansion Units are compatible with any tall or short shelf combination within The Shelving System.

Short expansion units are compatible with any tall or short shelving system.
Each middle shelf (not the fixed, top and bottom shelves in a Tall Shelf or the fixed bottom shelf in a Short Shelf) within every Shelf has three height options, allowing you to easily adjust it up and down in order to fit your most prized possessions perfectly. Resting at their center heights, each individual shelf is 11 5/8" from one another and you have the option to raise or lower them 1 1/4", based on your needs. You can also remove middle shelves as desired to create even more vertical spacing between shelves. The bottom and top shelves in any Shelf must remain installed at all times to maintain structural integrity.
Expansion units attach to one side of your current shelving system by sharing a set of supports. We created a proprietary track system to make expanding and adjusting quick and easy.
