The Sanus CFR1615 stackable skeleton rack lets you customize storage for your component system. 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. ) What's in the Box: 1. Left frame 2.
