I assembled this shelving unit in 2 3-Tier units. The Unit with the Casters is fine. However, there are a couple of issues with the one with the leveling feet. The threading on one of the TOP POLES (B) is longer than then threading on the other 3 TOP Poles (B). This makes one pole a little longer than the other 3. The 4 caps (I) included do not fit in the top of the Bottom Poles (B).The threaded inserts (J) were screwed into the base of the Top Pole (B). I contacted Seville and I was informed I need to assemble it following the instructions and they sent me a Video on how to assemble it. Unfortunately, the video showed how to install it as one piece using the Wheels. I wrote them back and indicated that I bought this item to be used as 2 separate units as indicated in the description. They ended up sending me 4 new poles with caps on them but they are not the same. They asked me if the product I have was made in Taiwan or Vietnam so they can send the correct parts. I told them Vietnam and sent pictures. When I received the replacement poles, they are made in Taiwan so they are not the same as the one I have. I cannot return the item since I no longer have the original box so now I am stuck with this and have the second unit with the leveling feet assembled with one pole longer than than others and no caps on top of the poles. All you can see is the threading.

Great product. Greatly increased my shelving capacity in my garage. Gotta admit, though, I have an easier time assembling things with nuts and bolts, than with those plastic do-hickeys. Wish you could explain why the weight limitations go from a total of 6000 lbs without wheels, to 800 lbs with wheels. Seems a bit extreme.

Perfect fit

The fit and finish on the last shelf I bought is not the same as the shelf unit I purchased 6 months ago. The item was poorly packaged and pieces were falling out of the packaging before I even started to unbox it. The main support posts were poorly threaded and when put together they had a bow in them, making it difficult to position the shelves. There are sharp edges everywhere the metal was cut and welded, and there was no sign that any deburring took place.

The box was taped together. After opening the box and examining the shelves it was obvious that it was a returned item. The round shape part of the shelves that fits onto the poles was so damaged that it would not fit. I am very disappointed that Sam's Club would ship out a returned/damaged item.

Great price and very sturdy,I would highly recommend this item.

Be cateful of damaged products being resold

Very easy too setup and my husband stood on shelf when erecting it and it supported his 200+ lbs.

These shelving units are great. Heavy, rolling and they come with shelf liners!

This shelf is amazing. The best I’ve ever bought. Easy assembly, no tools needed except a hammer
