Would give this a zero rating if I could. This shelving unit is nothing but junk. DO NOT purchase this unit - or any muscle rack shelving. It was a nightmare to assemble and is unsafe. No structural integrity and we finally had to make the shelving 3 high instead of the pictured 6 high due to our extreme safety concern. It took a solid day and two people to finally get the storage racks assembled - and we are seasoned DIY people. Then, to make matters even worse, we realized 2 days after we purchased the shelving (purchased 2 units) that the product was placed in the incorrect place at Sam's club. We thought we paid $39.98 for each unit (that is what the sticker on the shelf where the boxes were located stated) only to find out that these no good, piece of junk, unsafe shelving units cost us $64.98 each. If we had known the price, we would have stopped trying to assemble these unsafe shelving units and immediately returned the units to Sam's club for a full refund. Now we are stuck with unsound and unsafe units and will NEVER purchase anything muscle rack again.

The price is hard to argue with. But it’s super thin extruded sheet metal that is flimsy and has a tough time going together. Most of the pieces don’t stay interlocked, making assembly a pain. The other design flaw is the shelves sit lower than the frame. Anything that extends beyond the width of the shelf rides on the thin sheet metal. At the end of the day it does the job, but I wouldn’t buy it again.

Easy to assemble until you try to put on the upper half. It is a good design because I previously purchased a similar shelf assembly from Sam's which is sturdy and durable. This one is neither.The metal is thin and the components do not stay together. Will return and buy a better shelf.

The corner post are .050" same as the one's I assembled many of years ago, but the shelf supports that used to be .050" is much thinner (almost half the thickness) .028". When the pins go into the groove there is 20 thousands + loose which makes the not stay at the bottom of the hole, like they used to. The pins easily bend on the thin metal and cannot be installed into the slot without taking pliers and straighten them out. I tried using self drilling sheet metal screws to screw them together and it worked somewhat. There is no way the rack will meet it rating like this especially if it's 6 shelves high. The second rack I assembled, I used (2) 5/16" SS washers at the end of each shelf brace held in place by double sided tape, and it makes a secure joint (if you don't loose the washers). The other thing I did was separate the rack into 2 racks each with (3) shelves. This is the second set of racks I have purchased from Sam's within the last two weeks and both were no good. I have purchased and put together many of these same racks years ago before they started building junk. I would not recommend these to anyone, save you time, money and effort they are not worth it. It took a box of 100 self drilling sheet metal screws and a box of 5/16" SS flat washers and two days to put 2 6-shelf racks together where I should have been done with both withing 4 hrs or less. Oh yea by the way the joint to put the top section to the bottom is a joke, don't even try it.

Anyone claiming this is a heavy duty shelf does not know what heavy duty shelf is. I purchased many heavy duty shelves of this type and style, many from Sam's Club back when did sell good shelving. Over the years they have downgraded the quality of their shelving products so much that it's not even worth buying. This one so flimsy and cheap that loading to its "rated" capacity of 3600 pounds is just asking for trouble, possible fatal trouble at that. If you need heavy duty they stay clear of this product. Shop at a real industrial supplier like global because Sam's shelving is NOT heavy duty.

Trying to assemble this shelf is like playing wack a mole. The pins/rivets are way too loose, so every part keeps popping out when trying to setup the base. The metal is flimsy and folds, which adds to the frustration and trying to get the top part on (even on the ground) is extremely frustrating. I literally had every single piece pop out multiple times. I'm genuinely curious how this is even sold at Sam's. The 4 rack industrial shelf and stainless wire shelves are easy and sturdy to assemble, this monstrosity was not...moving it is also difficulty due to parts popping out and the flimsy gauge steel used. Save yourself some stress and avoid this rack. Hopefully Sam's will revise it in the future or discontinue it. I will never buy another one of these units again, it's just not worth the headache. I do not know if the 5 shelf model is as bad, but the 6 shelf is horrible.

Very sturdy and beautiful. I didn’t give 5 stars because some shelves was chipped
