"Bought 3 of these to make better/easier use of our closet, that has a 4 foot area that is difficult to access, because the doors don't go across the whole thing. I removed all of the existing rods and shelves... Reinstalled the shelf higher, allowing clearance for these units, while still having the storage we had before...(wider shelf) May remove shelves later, if we decide the top rack of the units are enough...still discussing.. Now, we can roll these out, and switch our winter clothes/summer clothes on different racks, back into the "hole"... We also, since we had 3 of these, decided to make two of the spaces with the little shelves a full length hanging areas, for dresses etc... I used a section of old rod that I removed from the closet, cut to length (41") to extend across the entire width of the unit...just shot a drywall screw into it through the provided rod holder. Then, used the extra 4 small shelves to make a shoe rack in the small space of the remaining unit. Warning... Think about what you want to do through, before you start... It's a huge pain to take it back apart if you change your mind.. or if someone ELSE does ;) What I learned...(better instructions) I built the base, put one section of tubes on, then stacked the shelves in the order I wanted them...except for the top rack... Then put the remaining tubes on...then put the little plastic things (wedges) on the top of the tubes...THEN put the top rack on. I learned this after wrestling with the first one.. Then, when you decide where to put the next rack, slide it up a few notches higher, and stick half of one of the wedges in to hold it up out of the way, while you carefully line up/place the wedge sets in place (level)...then, lift on the rack, remove the wedge you used to keep it out of your way, and drop it into place. Once you place the shelf, it's kinda tough to raise it back up, if you got one of the wedge sets in the wrong place...that's why I stressed that. My Wife LOVES this! She's got WAY more access to the clothes, and doesn't have to struggle dragging and pushing clothes up and down that 8 foot long bar....and can EASILY rotate the seasonal clothes to the nether regions of the closet... PS. If you have little kids, you might want to find a stud at the back of the closet, and put a hook, or shoot a screw with a big washer through the rack, to keep them from climbing it and tipping it over..." - Review posted on Homedepot.com
