These shelving units are not as robust as the similarly sized units I bought from Sams over a decade ago, but they serve the sam purpose and are a great value. I do think that because of the lighter material of the shelves/cross pieces that the structural integtriy of these units is more suseptible to damage and if one brace were damaged or popped out of place the entire shelf could collapse - so I would advise caution and put heavier loads near the bottom. Otherwise theses shelves are an unbeatable value for the price I paid.

Difficult to put together because the supports and shelves don't stay together while you're assembling it. The are constantly coming apart while you're trying to connect the other supports. Also it seems VERY DANGEROUS in the way it's designed...especially the top part connecting to the bottom half. I'm going to improvise and secure the unit using my own design, otherwise it's a hazard waiting to happen!

Cheap version of the old shelf. I've bought a bunch of these over the years but now that they have the Member's Mark on them the quality has gone way down. Everything that gets the Member's Mark is a cheap reproduction of the name brand. This is the same. You have to put the shelves in at the exact same time your building it or the vertical rails will bend because of the thin metal.

Cussed a lot putting this together, it should really be done with 2 people as the cross members kept coming loose as I was trying to lift the top section on. I am not sure I would put 600lbs on each shelf, that being said, I like the shelves and am very happy with the purchase. 84" tall is awesome.

Overall I am satisfied so far with this rack, but it really could be better. I like that the shelves are laminated, they are pretty sturdy, and overall meet my needs. The biggest issue I have is that during the assembly process there is much left to be desired. I bought two racks and out of the two this one was much more time consuming and frustrating to put together. No matter now much I tapped the anchors into place for each shelf it seemed any nudge to the one of the side beams would cause the opposite side to the shelf bar to pop out of where it was anchored in. What should have maybe at most took an hour to an hour and a half instead took me 3-4 hours to get to completion. I also feel that there could be a better way to join the top and bottom half of the unit together that is perhaps more secure and less of a pain to work with since you are using a shelf and it’s anchor system to join the two halves, especially after the headache of dealing with the anchors popping out of the bars at the slightest provocation.

This shelving was extremely difficult to assemble. It kept falling apart and hitting me. Using tape, I was able to assemble the bottom before the challenging top section. I assembled it using self drilling screws and that worked great. I would never buy this product again.

Our company saved over $2,000 when it purchased 23 racks for our parts room. The Sam's racks are less than the ones we considered from their competitor because they are not as sturdy but this a difference our employees easily and inexpensively solved. To strengthen Sam's racks our employees installed 1" by 2" boards on the sides of three shelves and attached the boards to the uprights with a metal to wood screws The boards were installed on both sides of the bottom shelf, the shelf that connects the upper and lower sections, and the top shelf. These boards provided the frame support the racks needed, locked the three shelves in place, squared the rack, and the upper and lower section are securely fastened together. After the selves were assembled and braced, they were installed in six rows and all of the racks were attached to each other and to a rear wall. The top of the rear upright was attached to the wall with a screw and a 1" by 2" board was installed between the uprights at the back or the rack. This rear board was installed in about the middle of the rack and it was attached to both the uprights and the rear wall. With a few hours of extra labor and about $50.00 in parts for screws and wood, our company saved thousands and the Sam's racks are now stronger than the higher priced ones from their competitor.

It is a very flawed storage rack. The two pieces dont really stack on top of each other. The rails also seem to be designed inaccurately because they just freely move even after hammering down. Makes it extremely hard to build. Once it is built with items on shelves its fine. Would NOT recommend trying to build as a single unit, the upper half would just sit on a 1mm curved edge and rivets would be pushed into the wrong orientation where a slight jarring would topple upper assembly.

I have purchased many shelving racks over the years, cannot recommend this one. The slots and braces really do not "lock" together and make the unit unstable in my opinion. Almost impossible for one person to put together because the the braces keep falling out.

Would not go with this rack ever again. VERY difficult to put together, as the rivets fit too loosely into the posts even after tapping them in. So, the thing falls apart as you put it together. Also, the short beams do not fit securely onto the long beam. There is a similar item that is about $20 more that I bought as well, and it is MUCH better. Everything fit well, and I put it together in no time. Only problem is that it is not as wide as this rack and is deeper, so the dimensions are not as good as I wanted, which was the reason for this rack.
