CyberPower 4POSTRAIL 4-Post Universal Rack Mount Rail Kit, Silver

Couldn't find a decent sliding rail kit so I finally opted for an adjustable rail. This one fits the bill perfectly. It's a good price for a very solid rail that holds the Cyberpower 2000va/1540 UPS without any issues. That ups weighs ~60lbs and the rails don't break a sweat supporting it. I went ahead and just ordered another for my first rack-mounted pc case. Ended up just resting that finished pc on top of the ups while I waited for the second set of rails to come in. No bowing, sagging or even the slightest hint of straining from these rails with the ups (~60lbs) and pc (~37lbs). My rack is 22" in depth and standard 19" wide. These rails adjusted easily into. I was pleasantly surprised that Cyberpower included m6 screws with a thin, flat head so that you can still use standard m6 screws on the mounting ears of whatever item you're resting on these rails. Since I don't suspect I'll be sliding things in and out often for the need of a sliding rail kit, I'll probably just stick with these as I continue adding other devices to my rack.

I've used a couple of sets of these in my small office rack and they do a good job. They are holding a 2u UPS and a 4u server. Nice cheaper set of rails with good strength.

The box came with the rails and some mounting hardware but no manual. I found the manual online, which shows how to mount both a 1U and a 2U UPS; however, the manual gave the impression that you should put in screws right where the UPS had screwholes. I have the CyberPower OR1500LCDRT2U (1500VA) unit. If you have the same (or similar unit), you'll want to hold on to the mounting flanges that came with the unit; you'll put them on the UPS and then the flanges will screw to the front of the rails. After looking at how things would fit together, I realized I needed to put the rails on the bottom of the two rack units where I wanted to install the UPS (the UPS would sit on it) and then put in the top and bottom screw through the rails; the screw for the UPS would go through the middle screw hole. I have a NavePoint 12U wall mount rack (which I leave on the floor), which encourages (through the use of optional horizontal supports) to keep the front and back vertical rails to a maximum of 16.9 inches (430mm); however, these rails have a minimum length longer than that, so I had to take off the horizontal supports and move the vertical rails farther apart. Aside from the initial uncertainty on how to mount the UPS and the rail, it seems rather sturdy; I like that the rails themselves have screws in them for extra durability (although I know some people would rather not have screws).

Built like a brick, straightforward to assemble, nice adjustable range, reasonably priced- what’s not to like? I’ve tried it all. And I come back to buy this one here. The cheaper off brand options don’t give me a lot of confidence and aren’t very sturdy- sure they might be ok for a 1U half-depth rinky-dink 4 disk NAS, but there’s no way I’m putting a 4U beast on the cheap mounts and risk catastrophe. Not worth it. (These will support a heavy 4U chassis just fine. I think their spec sheet says up to 3U, but as long as there aren’t 72 3.5” disks in there you’ll be fine) The sliding rails everyone gets excited about in my opinion become more trouble than they’re worth to get clearances just right and sometimes the server case doesn’t have a serviceable hatch in the right spot to make it useful anyhow. Most of my servers and arrays are self built and the tops which affix in the back and sides- won’t do you any good to have sliding rack mounts in this kind of scenario. So, that’s how these cyber power rails became my defacto standard. I can’t think of anything I want that these don’t have.

I had to mount a device in my server rack but I have racks that are more like relay racks and have threaded screw holes and the depth of the rack is not typical. So typical rails have issues. I bought this set of universal rails knowing I was going to have to make the device fit them and the rack. The rails worked as expected and I would use them again. I wish the screws that adjust depth were more flush but that is minor.

They really hold all the weight that is being claimed. Fits my StarTech 42U open-frame rack just fine, with no alignment issues for the rack's holes. Comes with cage nuts and the associated screws. I knew that when I was buying the item, but I wish that the rails were black.

It starts with the fact there is 0 documentation in the box. Not too worried, seems pretty straight forward.. ..until I realized almost all of the rails (minus one whole rail!) were practically drilled together, so I just could not back the screws out to adjust them. On top of that; - they seem to get SUPER dinged up scarily easily - they are not at ALL sturdy. The one I was able to get installed properly flexes super easily under minimal weight no matter what Oh, probably should end with the fact (though probably already told by the images) these aren't actually really rails. These are just glorified shelves pretty much. Which I'd be totally fine with.. had the product actually worked in the first place.

Very sturdy and not at all flimsy. I believe it would support close to the advertised weight. Does not fit my AxcessAbles 4-post rack cabinet. Its too long/deep even at its shortest length and does not sit flush to the posts which does not allow enough room for the rack mounted UPS. See photos. Otherwise, it seems like an excellent set of rails. I will be returning it since I can't use it with my rack cabinet.
