Silverstone Technology RMS05-22 Tool-Less Ball Bearing Sliding Rail kit for Silverstone RM44 / RM51 rackmount Chassis, SST-RMS05-22

Very solid rails that fit my StarTech 25U rack with 32" of mounting depth perfectly. The tool-less rail install is quite nice and easy to do with just one person, which I do appreciate. Once everything is said and done, it feels solid enough, but the mounting clamps on either end give me some pause for how long they will hold up. It'd be best to use some mounting screws on the ends I think. These rails slide well and are a much better experience than the iStarUSA generic rails I tried using a few weeks ago with a Rosewill case. That being said, they are pretty pricey! The iStarUSA rails had beefier ball bearings for sure for less than $70.

For the uninitiated, King Slide is quite a well known brand in the datacenter world, they are used by OEM's in the latest GB200 NVL72 racks. Price is good, quality is good, weight capacity is listed as 77lbs way more than enough for most applications, very stable with proper alignment. Ensure you're using these with a compatible chassis. 1 year warranty should you need it (you won't).

Definitely overpriced. It works, but you really need to secure it with screws. If you just use their clamps, it will likely detached and the server will fall to the ground. It happen to me. So don't trust those clamps. Use screws. They don't put enough screws in the box to secure it to the rack posts. You would need at least 4 screws. It comes with 2. Fir the price man, just shove there more screws. Stingy fellas

If you're homelab'ing - and got a rack set up, I recommend these rail kits. It took all about 5 minutes to get the slides on, mount to my rack case, and slide it in. Super easy, and sturdy.

Great product, super solid and smooth. I spoke with customer support to figure out an issue I was having on my end and they were very responsive, and got the issue addressed fast. I believe Silverstone as a company is worth any extra penny.

Bad QA, missing 2 bearing balls on one of the slides, resulting in an inability to extend inner member out of slide

Contrary to other reviews, these rails do have an adjustable depth from 24" to 37". They were pretty easy to install and though the instructions could be a little better, they were good enough for me to be able to figure out how everything worked.

Great rails, though a bit light on documentation. They *only* work with a 24" depth; I had to adjust my entire half-rack to support them. Once I did that, they were very easy to install. Indeed they are toolless.

Wayyyy too expensive. I paid $236 for these sliding rails. Other universal sliding rails sells for less than $70. But you can't use universal rails on Silverstone cases, they purposely design them to fit only their patented models so they can make more money after you already overpaid for a $1000 rack case.

Genau das was man erwartet. Sauber verarbeiter, Vorsicht die Kanten sind scharf. Einfache Montage und wirklich ohne Werkzeug. Hält was es verspricht. Zwei Sterne Abzug für den Preis des Produkt. Für Blechschienen über 100€!

I built a new server with a Silverstone RM44 Case prefer to use sliding rails. I found these problematic to be honest. The instructions aren't the easiest to follow and you need to pay attention to the mechanisms to figure everything out. The inner rails had some spring leaf latches on them that got jammed. I nearly gave up, but eventually, I figured out that you can use the provided screws to secure the inner rails and rip the latches off. It worked for me and I'm happy now, but there's a better way. When installed they are good rails. So I'm happy now.
