Technology RMS03-26 Tool-Less Ball Bearing Sliding Rail kit for rackmount Chassis, SST-RMS03-26, TAA Compliant

I should be writing this review about myself and my poor planning. Or this is a review about trusting Amazon's "commonly bought with" links which I never use, and never will after this. I was going to write this review knocking these rails for being too long when all my other rails across numerous devices have all fit properly in my custom 4 post rack. Thats part of my struggle, my rack is custom and I'm not sure what the correct dimensions of a typical 4 post rack are, other than mine is sufficiently deep for numerous other devices including a long 4U server case. But allegedly (according to other review) there are multiple rail sizes (26 v. 24). Anyways, these were literally <1/2" too long and wouldn't fit. But I was determined, and there's actually a section of the slider that can be drilled out to slide further in, and some bending to get it to slide yet even further in, and then with some torque and sweat and determination I mashed these things into my rack. No impact to functionality and they are in fact nice rails, the levers to slide the case back in both push the same direction, not opposite because they used the same flipped mechanism on both sides like my iStar rails. So, pointless long dumb review point, do your research and don't trust Amazon. I should have just bought the "24" which appear to not be here on Amazon.

Installation is really easy, however they say it is just a clip and go rail, but the design is really dangerous. When I slided in my server chassis into the rails, the front clips detached from the rack and my chassis fell down. I think I died right there. So, securing the rails with screws, it's mandatory not optional. And why did you only include 2 screws instead of 4? I always miss some parts whenever I buy Silverstone.

This rail is solid as long as you have a full length rack at least ~30 inches deep. If you have a smaller rack this won't work. It's sort of annoying to be honest because my Silverstone case (RM-502) is only 22 inches deep yet it requires this massive rail. The rail itself is 26 inches long. Would have been nice to be able to mount my case in a Rack that's 24 inches deep (23.7) since that seems like the next common size up from 19 inches.

Rails worked great once I modified them. They're about a half inch too long for my 26in rail space. I ended up having to Dremel out metal cap to the adjustable bit and slide it in more. Not happy about the extra work but it is what it is, ding them a star for it though I didn't find a 24in option on Amazon or on the Silverstone site

I received the RMS03-26. The sliding rails look nice and are sturdy. Unfortunately the documentation doesn't clearly state that the 26" (66cm) rails actually start at 28 3/4 (73cm) and can't actually be used in a rack system with a depth of 28 (71cm). As such, I'm not stuck having to order RMS03-24. I should have done better research ... so my bad. Be aware that "26" in "RMS03-26" isn't a valid size starting point as one would expect.

These rails are a perfect fit for my router case. They slide nicely. I would have given then 5 stars if they were packed correctly. One side was in foam and arrived in perfect shape. The otherside did not have foam and one of the plastic yellow locks was broken into several pieces. I called the manufacturers U.S. customer service number and asked them to send me one. They did and it arrived quickly. These do come with the adapters to mount into racks with round holes but I will not be using them.
