Advertised as rack mountable but not compliant with standard rack hardware
342052
Advertised as rackmount, but isn't (ie between 1U and 2U in height, rack ears don't fit standard mount holes).  Vendor doesn't support and sends you to manufacturer, have yet to receive response from manufacturer.  If rack compatibility is important, continue shopping, or be prepared to manually customize to make it work.

This rack unit will work, that is, if you are using Grade 8 screws. The screw holes in this rack system are correctly spaced, and semi-correctly threaded. The reason I say this is because I can tell when putting a screw in, that the threads are indeed 10-32 like they are supposed to be. Like any other piece of rack equipment I have used. BUT the screws don't fit! No matter how much you try, the screws do not fit the unit properly. And if not careful, you can easily break a screw off inside the hole. Making it nearly impossible to remove, and making that rack space un-usable.

I believe that the problem spurs from the fact that the manufacturer decided it would be a great idea to powder-coat the frame (which is very nice btw)  AFTER they tapped the holes. This causes the powder coating to adhere to the threads as well. Which, in-turn makes it impossible to screw in something without re-tapping the holes.

The racking system is very difficult to use with this problem. But, I guess you get what you pay for.

The unit is fine and works as advertised.  I didn't realize that it did not have the mounting tabs (the picture showed them) so rack mounting is difficult.

The bike rack itself is of great quality construction, has a solid weight and quality to it, but it doesn't fit all bikes!

For instance, a woman's bike will NOT fit without an adapter. (The product description doesn't make this clear).
Also, I wanted to mount 2 kid's bikes, but they don't fit either! They're the standard 20" (tire size). The product description doesn't make this clear either.
Essentially, I bought this to carry our beach cruisers...but a male beach cruiser won't fit on this because the top bar is curved - this rack is made for bikes with a straight bar.

Basically, this bike rack is meant for standard men's bikes, 24" and above. Won't fit my beach cruiser, wife's beach cruiser, or our kid's bikes.

Good product otherwise and great price.

The rack itself is pretty sturdy and will work for what I need it for.  However, it came with pretty cruddy mounting hardware and there wasn't nearly enough hardware.  I had to spend another $35 for hardware from ACE to mount everything.  If you buy this you should know that you will only have enough hardware to mount about 5 things!

I bought this UPS thinking I could rack mount it.  WRONG!  The manual I downloaded before I purchased it says it includes 2 rack mount rails.  The unit arrived with no rails and the manual in the box does not say anything about rails - only brackets.  Very misleading.

Great quality hardware kit but the mounting distances are not at the standard 16" as a heads up to anyone looking to purchase it

I really like the construction of this rack, so when I received it I was excited to mount it on my vehicle, BUT the mounting plate would not fit the tire mount. I was so disappointed. So I had to return it and the Amazon return policy is unbelievable. It was quick and efficient. I don't think UPS had the pkg. on the truck for more than a few hours when I was notified that my full refund was already taken care of.

The page that I ordered from failed to mention that the feet did not come with it !!  $300 MORE AND YOU CAN MOUNT YOUR RACK !!!!

I bought two of these because they are actually fairly well made and easy to put together.  However, when I tried stacking them on top of each other I noticed that the holes on one side of the shoe rack were smaller than the pegs they provided to make them stackable.  Not sure if it was just the batch I got or not, but it's pretty unfortunate since they are advertising them as "stackable."  If you're just looking for one shoe rack, you could do worse, if you're looking for stackable, buy at your own risk.

unable to mount my son and wife bikes because they are not the right type of bikes for this rack.
I have to buy another two tubes costing more than $70. The fasting rubbers are hard to handle too.
Overall it is OK. It is too late for me to return the rack. I should buy the Platform-type if I had some homework done before purchasing this one.

Be sure to check the rackmount kits found here https://www.mylive-tech.com/product-category/computers-gadgets-and-hardware/networking/networking-rackmount/?ref=1

Depending on your project these could be a better alterative to the standard metal brackets

The hardware is too large for my door frame. After working around the problem the bar will not fit into the mounting hardware. This is a seriously inflexible design.

Disappointed!  Sturdy construction but the rack doesn't hold the advertised number of bottles.  The support slats are too close together to support anything other than narrow bottles such as cab, rioja, Sangiovese. If you have bottles in different, wider widths then this is not the rack system for you.  Poor design.

I installed the bicycle rack on my garage wall about 8 feet off the floor. Installation was relatively simple, and took about 30 minutes (not counting extra time to buy better mounting screws: see below). Although I rated the product 4-stars, my experience leans to a 3-star rating or at least a desire to find an alternative product for equivalent price.

This bike rack should not be described as holding six bikes. I agree with many previous reviewers that the rack holds a maximum of four bikes so much so that the seller should seriously consider changing the written description of the item. Rack is difficult to use because holding heavy bikes over your head and balancing tires to lean perpendicular to the wall is strenuous. My garage wall is hopelessly blackened with tire marks. Bikes are unstable on the rack. Bumping one of the hanging bikes will cause a cascading tangle if not bikes falling off the rack.

There is plenty of room for product improvement. The provided mounting screws are too small. I had to buy four " X 2 " lag bolts to assure the rack would be secured to the wall under the weight of four bicycles. The hooks easily fall off the horizontal bar when placing or removing a bike. What would it take for the manufacturer to add a small hex-head set screw to each hook, so that the user can tighten the hook to the horizontal bar?
