SilverStone TechnologyRMS05-22 Tool-Less Ball Bearing Sliding Rail kit for Silverstone RM44 / RM51 rackmount Chassis, SST-RMS05-22

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.

easy tool-less install to the RM52 and my server rack

The back side does not fit into my rear server rack holes. It may fit fine in more professional racks with better hole cut outs, but not my ebay 42U rack. I need to resort to widening my rack holes a little bit to fit it. It's unfortunate I need to resort to that, especially because the front of the rack has a different type of clamp that does grab on well.

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.

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.

A bit pricey, but excellent build quality.

The rails themselves sure seem strong, but I can't really tell how well they work because... they don't! Out of the box, one of the pair was totally jammed. The first step in the instructions is to disconnect the innermost piece, but it's firmly wedged in there. What a waste.

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.
