These are heavy duty metal roll around shelves with wheel locks. Bought 3 of these and each box had all the necessary parts to make assembly a breeze. They are food service grade metal so they won't rust. Also they come with the necessary parts so they can be fixed in place and with safety straps so they can be secured to prevent tipping . I am using them for my pantry, and tool storage in my lower level.

4th one we have purchased. When I purchased my first 2 at Sam's, they were 100% but weighing 100 lbs each I need help loading and Sam's is iffy to do that. I ordered the last 2 online and they arrived a bit late and one shelf on each unit was bent, so we used 1 fewer shelf on each. At 73 yrs old, delivery is my best option and then unbox and move 1 piece at a time. Returns are not feasible at my age with a box that was damaged and unusable. If you buy at Sam's, you can inspect the boxes for damage. Use in Garage and in attic for storage. Assembly is easy but you need 2 people.

Love these racks. Nice that the wheels come with them, last time i bought these at home depot (couple years ago), you had to buy the wheels separately. Sturdy, easy to put together, but be sure to check yout rack height with what you're going to put on the shelf before you tap them down.

M. M. 6-Tier NSF Wire Shelving is a great product. I put it together, loaded it up and rolled it all around my basement. My only problem was one of the female threads in one of the pipe legs would not accept the male threads. I told the company about the problem, and they immediately replaced the bad part. I gave this a 5-star rating because female thread problems are hard to see.

These shelves are great. I love the size and quality of the shelves. I’ve also never seen this kind of shelf system with liners - they are awesome! I can place small things on the shelves without worrying about them falling through and I can sit things on the shelves and the sit even. Never knew I needed them before, now I don’t know what I’d do without them. The only negative I have is that the box is VERY heavy! I’m so glad I had it delivered rather than pick it up at the store. I was barely able to get it in the house, and I got two of them!

These shelves are great! Sturdy, easy to put together and customize - and change as needs change. This is my 5th set of these shelves. They are now lining a full wall of my garage and I have not had any problems with any of them. Was able to put this set together solo, but it is infinitely easier with a second person. I have them all set up with the wheels, but haven't yet used the wheels to move the shelves (haven't had a need to move them) so I can't say how easily they move. I think if I do ever move them, I will take the wheels off all but one of the shelves (leave them on the one covering my circuit breaker panel) because the weight the can handle increases greatly without the wheels. My only issue with the shelves is the shelf liner that comes with it. It tends to move a lot when loading things on the shelves. Once they are "anchored" by items being on the shelves, they stay put, but it can be a pain when initially loading up the shelves.

Overall a very good value; the thin plastic shelf liners are a good attempt to stop items from falling through the shelves but they are so light weight and flexible that they slide around on the shelf as heavy cartons are repositioned. Good idea the woulld be improved if it was made of stiffer and thicker material.

Very well built, and attractive units for the price . Uses tapered plastic rings to support shelves , which the ring design could be improved. The rings can come loose and fall off until you get the shelves locked in . Once shelves are locked in it’s solid and won’t go anywhere. Use two people if possible to rectify the issue with the plastic rings and it will be easy to assemble. 5 stars for quality and value overall.

Sturdy metal shelves. Easy to assemble and change the height of the shelves. Wheels available to use on the bottom which makes it great for moving them around before and after you've loaded the shelves. Depth isn't as deep as some of the other shelves on the market, which is what I was looking for with limited space in the garage.

These were to complement a previous purchase - They didn't match - They were much stronger and had an extra shelve and does this sound as though I don't like them. NO, NO, NO! My thoughts are these are much better than those I had previously purchased and used, and I gave them 5 stars - these deserve 11 stars! With choices of using wheels or stay put pads these wire shelving units are super.
