Question: Can I cut 4" off the top posts and move the top shelf down? I want to put this inside a bedroom closet and the coat rack is at 68".
Document: Assembly is not as difficult as some have written. It can be frustrating when joining the posts, but not difficult. I just finished putting one together - by myself - in less than 10 minutes. 4 of the 5 shelves are adjustable, but you are required to put one shelf where the posts join, as the shelf rails hold the two parts of the posts together.
A big sturdy shelf at a good price, and if you have Amazon Prime it ships to your door from free in 2 days. No trying to wrestle it into your car at the big box store. It's a BIG BOX and very heavy. TIP: Built it right by where you want it to live for it;s entire life. It's next to impossible to move around once it's built. I consider that a plus.
The shelves themselves are very sturdy and seem like they will last. I use them in my garage and have put some very heavy items on them with no problems so far.Assembly was another matter. The instructions are easy to follow and understand and the assembly is very easy until you get to the part where you join the posts. The four posts that serve as the corners are not one piece each, but are actually cut in half to reduce shipping size.
... how to put the two sections (top and bottom) together, I was more than pleased with the product.Used for storage in our den closet, holding miscellaneous stuff from Christmas decorations to CDs.
I was excited to receive the 5 shelves I had ordered, however once I attempted to assemble the shelving systems everything went downhill. The instructions were clear, and I didn't mind the fact almost every single shelf was broken - what I did mind was 1/4 of the corner posts wouldn't line up properly to allow the two piece shelves to be stacked into a 5 shelf system. Instead, you would get 3/4 stacked, and the 4th one would always slide down.
We have 5 of this exact shelving unit and 6 of the 24" units. I'm about to order 2 more. They are easy to put together (it does help to have 2 people due to the large pieces) and are perfect for storing our inventory. One reviewer mentioned the fact that the 4 beams are each cut into 2 pieces. This is true however I can't tell that it makes any difference in the sturdiness of the unit.
I had a little trouble trying to get those posts to stay together, but I used my rubber mallet and hammered it on. The rubber mallet was the only tool used. It looks a little un-stable, but I've had no problems with it thus far (have all my drinks, water bottles, and water jugs on that shelf). I put this together alone, but it would have been much faster with another person.
This rack is great. I went from having a small galvanized shelf the was loaded with stuff and having other things just set along the edge of my garage to having plenty of room for almost everything on this one shelf. It's easy to put together and looks like it will last a long time.
I ordered this storage rack a month ago and am very pleased with it. A friend of mine helped me put it together and it took less than 30 minutes to unbox and assemble. It's wonderfully sturdy and holds a lot of weight on each shelf. It's doing the job that I needed it to do, and I couldn't be happier. Might purchase another if the need arises.
I've put my large spice containers, rice containers, 2-liter sodas, 24 ct water bottles, and much more on these shelves. I also have put my shop-vac and steam cleaner on top to clear up space. My dog food container goes on the bottom shelf. I'm surprised on how sturdy this is.
