We purchased 3 of these and had them installed beside each other in our garage.  Saved $ purchasing this way rather than the 3 unit option. They are perfect!  Large units and very sturdy.  Love the adjustable shelves.  We put them on a wood base, didn't think hanging them would have enough support.  I ordered on a Friday and they were delivered to my door the next Tuesday, so fast and easy.  They are VERY heavy, would have hated to have to bring them home from a store.  Arrived in perfect condition.
