Rackmount Sliding Rails Kit - for 2U-8U Chassis, 18" to 25" Depth

Was a bit of a mess to install, but these rails work well and fit my server's chassis just fine. They seem to be sturdy a month in, so I am happy with them.

These are great rails, tough, strong, sturdy, well designed. Contrary to what some say, they don't cause case to be offset in your rack system, the case you pair with your rails causes you to be offset. Buy the right case with the right mounts and as you'll see in the pic/video it fits perfectly. The case I bought was the rackchoice 2U case (https://www.amazon.com/dp/B0BN1XBL2R). This case had the exact same threading and holes lined up perfectly with these rails. Though I suspect all cases will line up perfectly as the holes on the part that screws into the case are slider holes so they pretty much line up with anything. These rails provide a nice click at the end (which you can see in the video) that holds the case firmly against the rack. But what's nice with cases like this is there are extra holes like in my video which also allow me to screw it in if I'd like to for security reasons, etc. The reason I deducted one star is because the hardware they sent seems to be lacking the necessary M5 nuts needed for the mounts. I bought two sets, both seem to be missing this, but perhaps I'm the one missing something. Fortunately I ordered these M5 nuts that screwed onto their hardware per their instructions just fine: https://www.amazon.com/dp/B0CNCKPC45 Since you're buying the nuts anyways, I found better bolts than what they offer that take a little shimmying to fit the head of them through the opening provided, but they mount the rails better than the ones they sent, they clear the slides no problem and they also work with these same M5 nuts. Here are the bolts: https://www.amazon.com/dp/B0DZ2H7N25 So for $15 in additional hardware, these are the best sliding rails I've installed for any of our clients. I didn't have to drill my own holes in the case, I didn't have to do any weird setups, and the way they mount allows the case to sit flush against the rack as if the sliders weren't there (see picture/video). People have complained they are too thick, but they mount perfectly behind your rack without any sticking out...so if a case will fit on your rack, it will fit on these rails. I think people failed to tighten them down while holding the rails tight to the outside. I did that and zero part of the mount sticks out. Honestly I think the easiest way to solve this, and I did this for the 2nd pair, is tightened them to the rack, then hit it with a rubber mallet afterward which scoots it to the outside and wala, mallet magic.

Works great easy to install and compatibile for my 4u pc. Good quality. The screws given are exact number so careful not to loose any.

The slides themselves seem well built, but I ran into several issues during installation. The tolerances on this kit are not accurate. I ordered two sets in case the first was defective, but had the same experience with both. I was able to get them to fit, but they are a millimeter or two too wide, which causes the slide to catch. I may need to grind down the front rail posts slightly to resolve this. The instructions are poor and include a lot of hardware that is either unused or not referenced at all. I also had to buy different pan head screws to attach the slides to the server chassis, as the included screws were too large.

Missing the nuts that should be included to attach the rails to the ears. The quality of the metal it's constructed from is very poor. The fit isn't great because the rails are so thick. The screws included are also made from cheese, stripping before proper torque can be applied. I had to replace all the missing and low quality hardware to complete the install, at which point I could have just bought a proper set of Supermicro rails that are made from usable material.

Not enough screws and most of them were the wrong size, it's quite hard to line it up, but once its mounted, seems to be holding up for the last 15 or so minutes. I strongly recommend you find another type of rack and don't do what I did and buy in a rush, since this type of rack is a pain to mount, but it works, and it does what it supposed to do, just that, there are better

Fits well on my Silverstone RM41-506 case.

I thought I'd give these a try with a full size 29" depth rack... they fit, but just barely. The reach L-bracket is as far back on the rail as I could get it. Definitely not ideal, and not sturdy enough to hold anything of significant weight at that point - and they won't slide out very far. The product page does say these support up to a 25" depth. Even at 25", these still wouldn't extend out as far as some others. These would work best on smaller depth racks, allowing the mounted device to slide out far enough. Anything else and these are likely only good for smaller devices, like a switch or similar. They are well greased though, and the sliding operation is nice and smooth. They do seem well built, but I think you'd need about a 20" depth for these to work best. Also, it doesn't seem mentioned on the product page anywhere but the mounting hardware (screws) that come with these are built for M4 cage nuts rather than M5.
