Great budget 1U Cantilever Rack Shelf.
355840
Does not support the 80 pounds claimed in the description, but overall a good cantilever 1U shelf.  Just don't over load it.  Not robust enough to handle my NAS units, but works fine to hold two micro systems - 1 X Dell Micro 3020 and 1 X MAC Mini.  Also good for holding a pair of desktop network switches.  My NAS units are a 2 bay Synology, which was fine, but I also have a Netgear ReadyNAS 314 with a 4 bay expansion.  8 standard NAS 2-3 TB 3.5 inch hard drives are heavy, and not weight distributed.  I ended up going with one of StarTek's really heavy duty 250 lb full length adjustable rack shelves to handle that load.  That said, this is a great low cost 1U cantilever in all other respects.

I bought a "less than perfect" shelving rack for about half-price.
There were virtually no imperfections, assembled quickly, and adequately met all my expectations for appearance, ease of assembly, and intended use. It arrived in a timely manner.

It is surprisingly well built plastic shelf rack. Bought it to stock miscellaneous items in my garage. Easy to put together, good quality plastic. For extra sturdiness you can even fix it to the wall. For the price can't really go wrong with this shelf unit.

This is a great deal on functional and sturdy shelving. It is super simple to put together (takes about 5 minutes with 1 person). It also has a very heavy maximum load capacity.

While it's not the nicest/heaviest rack out there, for your $, you really can't go wrong with this rack. Unlike practically every other rack at this price point, the 3107.1 uses heavy gauge angle iron steel runners to hold the dumbbells so they don't bend. The most burning and difficult to answer question I had when buying it was "how many bells will it hold?". Well, if you want to max out the space on each 48" rack within an inch using standard rubber coated hex bells (CAP, etc.) split in relatively even weight ratios from 5-100, you can fit pairs of 5s, 8s, 10s, 12s, 15s, and 20s on the top rack, pairs of 25s, 30s, 40s and 50s on the middle rack, and pairs of 60s, 80s and 100s on the bottom rack; 13 pairs in all. Standard uncoated iron hex bells are marginally smaller than their rubber counterparts, so the same denominations will also fit.

Great shoe rack for the price. Fits 4 prs per shelf. Fit behind door. Sturdy and easy to assemble.

I wasn't sure about this, but I went for it and I'm glad I did. This unit was easy to assemble (I have experience, so might be a little slower for a first-timer, but instructions were helpful). The piece is actually pretty sturdy! I was pleasantly surprised. There was an issue with part of one of the shelves was bent, but it didn't affect the function or assembly at all. I am very happy with my choice and it was much cheaper than some of the alternatives I had considered. There is only one thing I want to point out, and it's that the rear vertical supports don't have the twisted details that the front does, but it's not a huge problem, or even noticeable unless you're looking...but I thought shoppers should be aware. Anyway, I would recommend this piece!

These are great shelves for the price.  I have some of the ones from Costco, and also some from Lowes.  These don't appear to me to be quite as heavy duty as the Costco brand, but they will do just fine and are much cheaper.  I am using them to store a variety of items, some heavy, some not and they are doing the trick for me.  I purchased two, and am getting ready to order two more.  Great deal!

I wanted a nice-looking stand that did not take up a lot of room.  Plus, I didn't want to spend a lot of money.  This stand fits the bill perfectly.  The shelves are made of thick, blackened glass which is beveled along the outer edge. The assembly process is extremely easy. NO TOOLS are required.  It took less than 20 minutes to assemble (and I was taking my time). The shelves are separated by 4 cylindrical, metal tubes. These tubes come in 5 different lengths (the shortest tubes must be used for the legs). The instructions tell you to use the shorter tubes toward the top of the unit and the longer tubes toward the bottom so that the bottom shelves will have the most space between shelves. But for my particular set-up, I wanted my frequently used components to be on or near the top of the rack where they would be easy to reach. So I customized this rack by installing a set of the longer tubes toward the top of the rack. This allowed me to stack my components to my liking. The point I am trying to make is that you can choose how much space you want between the shelves by selecting the appropriate tubes. And even though most of my audio/video components are stacked toward the top of this rack, the rack is still very stable and will not tip over. This rack is very sturdy, it looks classy, and my components easily fit on the shelves without hanging over the edge. At the price I paid, this was a VERY satisfying purchase.

Nice heavy duty shelves that will hold just about anything you can fit on it. Very simple to put together, a helper to lift upper shelves makes it better. I did not have any packing issues as some have noted. It was packed well and no damage or missing parts. Will probably order more of these in the future.

This rack is easy enough to set up, I had it ready for me to load it with all my art supplies in a matter of minutes.

Once I loaded all the heavy items on the bottom shelf, the rack felt quite stable for me to load everything else on the other three top shelves. And the price just can't be beaten.

Great shelf unit. Just what I wanted for the bathroom. Went together easy except for one screw.

A client of mine needed to put a LCD monitor on their rack to use for audio/video purposes, and rather than spending upwards of $1k for a rack-mountable LCD, I suggested a shelf like this one. Installed it for them in about 5 minutes, sat the monitor on the shelf, and was done. The shelf holds it just fine, and it appears that it would more than likely hold even more weight than the monitor. Not a bad price for it, either, considering local dealers of this type of equipment easily charge twice as much!

Great shelf for the price. All part are labeled so its easy to put together.

These are great for the side wall of my garage.  Being only 12" deep, they don't take up valuable car door opening space.  I ordered three shelf units that were delivered almost next day and in perfect condition.  The first shelf took a good hour and a half to assemble.  The second and third only took about forty minutes each.  I'll be ordering another two today.

A lot of the reviews are a bit harsh for the price paid.  These are not your three minute assembly plastic shelves (all of my plastic shelves sagged and looked ugly after a year by the way).  You will need a screwdriver and some patience.  I did not have to drill any new holes for misaligned screws.  Some twisting was required here and there but it all went together.  The only useful information in the instructions was which part of the shelf was the front and back.  Other than that, just look at the pictures on the box.  A cordless drill with an adjustable clutch was very helpful in snugging up the screws after leveling the shelf.

I don't know about 750 lbs. but these can easily hold several hundred pounds if properly distributed.  The bottom two shelves easily handled three 24-pack Coke/Pepsi cubes each.  I left one shelf off and only used six for more space between.  I plan to add the extra shelves to another section to make a cheap wine storage rack in a utility room.  These can be joined together side by side along a wall if needed.  There were plenty of nuts and bolts left over for something like this.  Be sure to put a screw through the back of one of the shelves or side rails to anchor it to the wall to prevent tipping.

First off you have to check your expectation at the price level of this item. For this price point it is really good.  I have a Metro Racks from Container store and they cost 4-6 times more.  So that is what I'm used to.  By comparison this is flimsy--but you have to put it in perspective of cost. The frame of the shelf is nice and strong, but the grill that makes up the shelf is much thinner metal.  I can stand on my Metro racks... don't try that with these. They will bow under too much weight.  Because the base doesn't have as much heft, I wouldn't pile too much on top of the unit as you would encourage it to tip over easier.  Assembly was identical to the Container store racks--and the instructions basically had STEP 1--attach all of this together. LOL.  I will definitely put some weighty clothes boxes on the base to ground the unit.

It's fine. Assembles fairly easily, though as some mentioned it's best to measure and determine which threaded holes to populate with screws prior to fitting to the rack, then leave loose until secured to the rack. Two small negatives: The shelf takes up 1U, and doesn't need to. Also the forward and aft brackets that attach to the rack appear to have different vertical spacing from our rack. So, only one screw per bracket holds the shelf (more than enough). The second vertical hole does not align with the threaded rack holes. Still, for the money it was a good choice for us.
