Not sure why the Members Mark shelving requires a small threaded connection, most of the others don't. Mine was likely a return, and had been cannabalized. Opened box, missing parts, even extra parts. I will say that working through the system, I was able to receive correct connections, rare.

Super sturdy & you can easily adjust shelves to any height & spacing you want. Easy to assemble, not tools needed. After attaching the wheels to the 4 vertical posts I would suggest installing a couple of shelves before attaching the the other 4 vertical posts.

I ordered two of these. I bought them because they were on sale for $20 off each. I was charged the full, regular price. I had to place a 20 minute call to get the $40 credited. The customer service lady in the Philippines acted like she did me a favor. One of the units arived with the box broken open. The zip ties holding the sheves together had been cut or broken. There was a connector piece pre-installed cross threaded. I had to use a vise and a rubber mallet to remove and straighten it. After assembly one of the legs is half an inch off the ground. I had to unscrew the wheel a half inch to make it level. It was assembled exactly the way the other legs were That is not how it is supposed to be. The other unit is as it should be.

I needed something study but movable for all my craft supplies. The large casters more easily on my carpeting but can be locked in place. The solid shelf liners are excellent to keep smaller objects from either getting caught on the wiring or dropping through. I am a 78 year old female but I was able to assemble it without any help from others.

This set contains the racks, plastic inserts for the racks, and a choice of rollers or feet for the base, It is the best deal that I could find for this kind of wire rack. I actually did not need the high weight capacity of these racks but they were less expensive than buying lighter duty racks (+ rollers). These racks roll smoothly and are very stable. No issues in assembly.

I now have three of these shelving units. I bought two more after about 5 years of only having one. Best roll about shelving and a great price. I use them in the garage to store larger and heavier tools and other junk. I like the casters so I can clean out the leaves and other crap the blows in from outside.

I ordered two sets of shelves. Both arrived damaged. One so badly that it could not even be set up. That one was returned. The other was set up and I did not notice until the following week that each of the six shelves also have slight twist or bend in them. It’s not bad enough to cause me the time to dismantle and deal w the return, but still disappointing. I ordered a Seville corner rack at the same purchase time and it was sooo much better quality packing, I believe that the poor shape of the Sams club shelves was partly due to the shortcut of packaging for such a heavy item. I bet there are lots of similar issues for people that have them shipped to their homes.

The only reason I gave this 4 instead of 5 stars...one shelf was bent when I received it. This wasn't due to shipping damage. The bend shelf was in the middle of the packaging. I was able to support it on the garage floor with a 2x4 and apply some of momma's good old collected cooking (my body weight) and with some carefully applied pressure, you can't really tell it was bent, unless you look really close. Other than that, these are well made, heavy duty and come with the option to use the supplied wheel kit or leveling feet.

Our family has at least eight of these shelving units! They are strong, sturdy, easy to assemble (and disassemble when moving to a new city like we just did), plus they come with shelf liners that are so necessary and helpful. I do not like to store ANYTHING directly on the floor, especially in an area where dampness can cause damage. I recently made a special trip two hours away to pick up another one of these shelves for our garage when our local store in our new city was out of stock on this item... that's how much we value this shelf and it's quality. Other stores carry 'similar' shelving, but don't typically come with the shelf liners which are precut to fit.

These high quality storage racks are fantastic for organizing your business or personal storage areas to make efficient use of space. I use them with bankers boxes in multiple layers against a wall as they are easy to pull away and look for stuff in back. I have some that are several years old and they show no signs of aging or corrosion.
