You can assemble the modular pieces in one of five different height combinations, depending on what you need. The braces are self-aligning, so you can easily fit the rack together without special tools. Slots in the braces let you wall-mount the rack for a more permanent storage solution. The rack ships flat with removable shelves blanking panels and hardware needed for assembly. (If you're planning to wall-mount this rack, check out Sanus' swivel support mount.)
