NavePoint 1U Adjustable 4-Post Rack Mount Server Shelf Rails Full Depth Set Black

Definitely heavy duty and good quality steel shelf rails! My purpose for these was to support the back end of a 1U server that was stupidly made with single screw rack ears on its front left and right side - not at all enough to support its own weight. The company did this because, big surprise, they want you to crank out more money for their custom sliding rail system which is hundreds of dollars. I have two of these servers so I wasn't about to spend so much for 2 sliding rail systems, especially when I didn't need them to slide out either.I found these Navepoint 1U shelf rails for a fraction of the cost and they do exactly what I needed them to! I simply used the two back pieces (the ones with the silver screw holes), racked them into the rear of my equipment rack, slid the server in on top of them from the front, screwed in the front of the server, and done! It sits perfectly in there and is supported well from the back.Now, I had hoped to use the two front pieces, flip them around and install those in the back as well for my second server, HOWEVER, they are too long - 20 inches - to fit in the rack without sticking out the front so, I couldn't use them that way. I had to buy a second set of this item for my other server but, didn't mind at all considering the cost and the money I was saving by going this route (instead of the sliding rail setup) anyway.Overall great item! I'll find a use for the shelf pieces I didn't use!

I purchased two of these to mount a few Infinband switches. The rack rails included with the switches only allowed the units to be mounted at the front of the rack, making it difficult to access the ports on the rear of the switches. These shelves are sturdy, and well made, and were a perfect fit for our needs. In this particular rack all units are installed with a 1U gap for air-flow. It should be noted thought, that they may not stack correctly if your devices are installed on top of each other without a gap, since the shelf portion below the device takes up some additional space.

This things seems like a decent chunk of solid metal, as there aren't any real mobbing parts.It was a tight squeeze for my System x3650 to slide in because the screws that join the front and back pieces of the shelf are on the inside, and the server was running into them with great friction. I removed the bottom set of screws, just using the top set, and I was able to get the server in the shelf.Next, there's a small lip where the front and back join. I decided to put the lip on the bottom, as I didn't want the server it help to run into it while sliding it in. But to my surprise, the server below the NavePoint rack was running into the lip and I couldn't slide it in all the way. I could have reversed the NavePoint and try that, but I just decided to drop the other server down a spot, and all was ok.What really impressed me was that I called up NavePoint support when the screw heads on the inside were presenting a real problem squeezing the server in. The person who answered was helpful, and even went and got a pair of rails and was able to understand what I was talking about. She offered advise, and then said she would pass on the note to the engineering team. I was very impressed with her.All-in-all, you will probably fair better if you have even a slightly smaller server than mine, but in the end it's doing it's job. It came with a selection of screws (though I would prefer more of the small-head screws), and packing was as to be expected for big chunks of metal.

I am not exceeding the weight limit of 110 lbs, and so these rails have worked great for my use at work.You cannot put anything flush below these, though, as they do hang a few millimeters below the rack level at which they're positioned. You'd want at least a cage-nut-hole of space, or just leave the 1u below them empty.I also don't adjust them ever. I'd love it if they were tool-less, but I'm not honestly prepared to pay the price for a tool-less version.

Purchased to replace Rosewill rails that were out of spec and did not work.The NavePoint shelf rails did not come with instructions, but were easy enough to figure out and install. Wish it would have come with a few more screws to attach the front and back rails together.

I purchased one of these just to use a support for resting heavier components on while I get them mounted in my rack. I mount these shelves upside down and then slide the heavier component on top of them into place to where I can secure them with their own rack ears. Makes it much more simple to load a 50+ pound rack component into its slot when working by myself.

It works

These rails are very heavily made and are easy to assemble and install. The only issue I had with them is that the screw holes were the wrong distance apart. When mounting this to my rack, I could put screws in the bottom holes or the top holes, but not both. The holes were about 1/8" (half a screw width) too far apart. This means I was only able to put one screw in the front and one screw in the back of each rail. I would not buy these again as they aren't truly 1U and will leave a gap.

Pros:- good build quality, heavy duty- lots of adjustment possibilities- all hardwares are includedCons:- a little expensive for just a couple pieces of metal- box was opened and seem like an returned gift from someone
