This shelf system was the worst I have ever put together. The keyhole locking system for assembly of the side brackets was too loose and kept coming undone as you were putting the other sides on. To place the top of the unit, I had 2 helpers and it still was very difficult. I bought 2 shelf units, but I'm returning the second one. Do not recommend this at all.

Shelves are sturdy, versatile and easy to put together. Other shelves I looked at were either too tall, too shallow, could not be used as two shelves or too expensive. I don’t think I would put 4000 lbs on them as they are rated but I do have plenty of heavy storage bins on them.

I put two of these together by myself. Can't operate a screwdriver, but with this unit, no need for one! It says it calls for a rubber mallet, but if you're careful enough with a hammer, you can tap the tabs into the holes. I did watch a video on YouTube (Solid Ground Staging guy) on how to assemble a 6-shelves Member's Mark shelving unit, and that helped enormously the first time. Very nice shelving unit. Thought at first it was all metal, and was apprehensive when I saw it wasn't, but it appears to be quite sturdy. Have loaded both units down with canned goods, laundry detergent (jumbo size), and cleaning supplies, etc. Shelf depth a hefty 24 inches X 48 inches long. Five shelves total! Under $70-can't beat that! Sure hope more come back in stock. Will buy at least one more.

The only way this will hold 800 pounds per shelf is if you are storing 2' by 4' sheets of metal. The composite board that goes on top of the side rails is flimsy and there is ZERO support in the middle. I can bend it with my finger. To make it work I'm going to have to put in 2x2 runners and top with plywood so that it will actually support anything other than stacks of sheet metal.

This item isn't always shown on the website but I did find ample supply in the Gladstone and Liberty stores. It is well built as the frame is metal and can hold up to 800 pounds per shelf. The product used to hold the items is made of pressboard and I did find two of them broken when I opened the box. However, I had all four shelving units loaded into my car by two Sam's Club employees but one did have extra tape on it and I think it may have been damaged beforehand. I exchanged it with no problem but note that the shelving is heavy duty so it will take some muscle. The price I paid was $69 for each unit. This is a great value compared to any other brand I have researched.

I like the shelves. I like the metal frames and the strong shelf materials. However, the corner poles have a plastic insert that allows you to stack the corner poles, so you can make the unit two poles high, i.e. allows for all five shelves to be put together as one unit.... but those plastic inserts are the only thing holding the poles in place and that plastic insert in small, cheap looking and does not feel like it securely holds the shelves in place. That, I really don't like at all... noting that in the past when I bought these shelves, that insert was metal and fit much more securely. So I'm disappointed in the new plastic insert... otherwise, I like the shelves.

For the price of $70 plus tax it's not a bad shelving system. It is 18 in deep 48 in wide and a total of 6 ft tall or you can break it down into two bench height 36 in shelving systems and use everything as an 8' long bench. This is basically what I did in my shop. I added plywood top on top of the given shelf that it comes with to reinforce it. But with everything all said and done it is holding up fairly well.

Heavy Duty Necessity!!! Strong, sturdy, large shelf that can be a side by side or a tall 5 shelves. Easy put together. However it took 2 of us to carry the box bc of it's size & weight. Nevertheless, it's so worth it! Most importantly, it wasn't overly expensive either!

It's so good that I bought over 30 for my 3D printers

Lovely shelves and they are fantastic. But good grief having to break each piece out of the diecast molding is absolutely tedious and so tacky. For over $100 for these having to break and twist plastic parts out of their molding is not acceptable. Obviously if you have some snips on hand this easy but we did not.
