StarTech.com 1U 19 inch Server Rack Rails - 24-36 inch Adjustable Depth - Universal 4 Post Rack Mount Rails - Network Equipment/Server/UPS Mounting Rail Kit HPE ProLiant Dell PowerEdge (UNIRAILS1UB)

Doddle to install, just pull them out longer than you need, screw one end into rail, go to other end of rack, adjust length by pushing/pulling as required and screw them in. Mine came with exactly the right number of screws and cage nuts (8) so don't lose any. Already have a pair of these holding a UPS so knew they would be good. This pair will hold my PC which is in a 4U case.

Prefect rail for all types of server rack equipment. Markings on the levels assist with placement

I have a long (100cm deep) home lab rack and needed to mount a short (45cm) and heavy Cisco switch to it. Since there is very little out there and I already have a StarTech rack, it made sense to continue with a StarTech generic, adjustable rail. Mounting the switch with the rails inwards, and sides pointing upwards, as anyone would reasonably expect, ended up pushing the switch and its mounts upwards by about 2-3mm, making it impossible to attach the whole lot to the rack. The only way that worked was to flip the rails so the sides were pointing downwards and the switch was resting on top of the rails, losing an entire 1U section to an empty slot where the rails now are. To top it off, the adjustable sides have two sets of screws to hold them in place and NONE of them work properly. The rails will slide all over the place as the screws won't physically tighten any furhter than they are when you receive the product. I am really disapointed in this product but am strapped for options available. I don't want to buy another one but have little choice if the problem arises with some other future components.

I can safely say this is the most pain in the arse rails kit I have ever had to install.

At the depth I needed of 590mm the adjustment slots were mostly useless and the middle holes to mount the crossbar(s) were obscured. I fitted this to my RackyRax 12u floor cabinet but the inner profiles behind the normal front profile mounting holes was hitting the bent back top edge of the rails, I had no choice but to take a few mm off the rack rail in the four places to make the mounting holes fit, no too happy doing this and it took ages. It cannot been seen now it’s all fitted though and it has no tweaked it at all, but my 4u server is only 20Kg or so. Hassle but no other choice to mount my server as I could not find any suitable rails.

Holds my 4U home server without issue, feel strong and stable. I do have a couple nitpicks but nothing that's a deal breaker for me. Assembly was easy, since they're really just extend then fit to server rack and attach (use your own mounting hardware though). I could not get the screws in the middle of the rails tightened down, as the instructions indicate, to fix the rails length though. Don't know if they were assembled wrong at the factory, or the hardware is bad, or what but it's ultimately not a big deal since they're affixed to the front and rear of the rack and can't move independently. The one thing that I do need to figure out though is some way to hold the server onto the rails, they're very smooth and it slides surprisingly easily forward and rear when doing simple stuff (like plugging or unplugging a cable). Granted a 30" server probably isn't just going to slide entirely off without warning, but finding some sort of grip tape or something to apply to the rails would give some peace of mind most likely.

Ottime slitte: robuste e facili da montare. Come suggerito in altri commenti, le ho montate rivolte verso il basso per permettere l'allineamento del server con le guide verticali del rack.

Nice and sturdy, I use it to support a big and heavy UPS in my rack

Diese Schiene ist zwar sehr teuer, überzeugt jedoch durch die gute Qualität und Verarbeitung. Alle Kanten soweit behandelt dass man sich wirklich ungeschickt anstellen muss um sich daran zu verletzen. Da kenne ich anderes. Was man aber beachten sollte: die Querstreben sind auch sehr stabil und gut verarbeitet. Leider aber auch ein paar Millimeter hoch. Legt man da einen entsprechenden 3HE Server hinein, ist er damit um ebendiese Millimeter höher und blockiert damit die nächste HE. Verschraubt man das Teil aber vorne und hinten wie vorgesehen, bietet der Ramen auch für echte Schwergewichte unter den Servern mehr als genug Stabilität.

Usla. Utrymmet blir för smalt och för lågt.
