Rackmount Sliding Rails - Kit for 1U-4U Chassis (Adjustable 18" to 25" Depth) 2 or 4 Post Mount Sliders for Server Case (Compatible with Any Standard Rack, Cabinet, Computer Enclosure) Tupavco TP1811

A few years back I bought a server rack which I didn’t realize was the networking rack in the depth was 17 1/2 inches. I subsequently bought a small server chassis and built a server in it, thinking that I could mount it easilyLo and behold, it’s been a nightmare. I finally found these rails, which are for 18 inches, in as you I also saw that it was a frequently returned itemBut I had to take some risk, because the server I had built was sitting on a shelf for almost 2 years. Honestly, it took a bit of effort, but I’m happy. I miss calculated and didn’t realize that the depth of my rack was only 17.5 inches, which means that this rail doesn’t exactly fit. I had to use a metal saw Trim some of the mountain ears, because they were overlapping because it’s so short. But after that, everything mountedOne thing I’ll note is that if you don’t use the hardware they provide for mounting those ears, you’re gonna have an issue if your server needs itself to be screwed to the rails, Which is why the hardware they provide is offset a little bitOverall, I feel confident this can hold the for you server, which isn’t too light. It’s been there for a week and it’s working well. The rails themselves are good, slide effortlesslyTook about 45 mins to install overall, and that’s with undoing the old rails I had.

Ok, how to explain why these have such a high return rate; they are not universal.They are basically just drawer slides that are to be mounted exactly like a drawer (via screws on the side of a case). The adapters for the drawer slide take up the 1U slot and are mounted on each end via cage nuts. The slides themselves take up about a two thirds of an inch between the rack rails which mandates that whatever you mount with these slides be that much smaller than the normal.To finish this off, there are no secondary 1U parts with this kit to allow you to again use cage nuts to afix whatever you need to slide out. This is what makes this kit non-universal.As long as you've a long case that is 3/4" smaller than the space between the rails and as long as that case has multiple screw holes along the side in a straight row, this seems to be of decent quality and may well work for you. Outside of all that, keep looking (I've yet to find an universal one).

Double check that the rack you want to put these in has front and back posts. Sigh. So, these went into a different rack and are carrying a 4U server instead of the 2U one that I really wanted on slides.The install was without drama (other than my rack mistake). Everything works smoothly. The build quality seems fine, but maybe strong enough to trust them with a UPS, if it isn't too beastly. The slides do have ball bearings. That's not mentioned in the product description. You'd expect it to have ball bearings, but you never know what a manufacturer is going to try to slip by you these days.

As another review posted on the 2U-8U version of these Tupavco rails, they are several mm too wide to mount a server to a standard rack. I was hopeful the other review would be wrong because shorter depth rails are a bit uncommon (needed for my 20" depth Echogear rack) and this seemed like the best choice. My 4U Chenbro RM42300-F chassis could not fit into the rails as designed, so I had to mount the ears behind the posts leaving them to wobble side to side. I can tell even with the added wiggle room this is still a strain on the rails because I can see them bowing slightly outward once I spent the 3 hours trying to get the chassis mounted. In the end I was able to mount it and it does slide in and out as I would expect, but it still bothers me that the ears don't wrap around the front as they should. Directions are also poorly printed, don't have an included hardware list, and are poorly written and confusing. If you find a better set of short rails that fit a Chenbro chassis and an Echogear rack let me know.

The instructions and the supplied hardware do not match the slides. The extentions are show with threaded inserts. The actual extentions have plain holes, rendering the hardware useless.The bigger issue is the slide releases. These a plastic. The plastic is so flimsy that it very difficult, if not impossible, to release the slides once installed. With metal releases, I would have given these 4 stars.

This is an okay set of rails for medium depth racks and medium weight items. The instructions were sparse, and while that might reflect a certain expectation on what type of person purchases these, they should still be better. I believe it is a stretch to expect to put much of any 4U items on this, as the provided connecting hardware does not look up to the task. The rails themselves are pretty solid, and the ball bearings are good.

It's a fine kit. Slides great. However, you'll need to provide some extra hardware and the instructions are TERRIBLE.

I bought this to fit a dell R220, but the holes on the unit were not placed properly. I believe these rack rails will not work on any dell servers from how the holes are mounted. Most dell servers are hardware free rack rails.

En general, son buenos rieles deslizantes para servidor. Sin embargo, hay cosas que me gustaría que mejoraran.Cosas buenas:- Aguanta una caja 4U con varios discos duros.- Se ve resistente una vez instalado.Cosas por mejorar:- Instalación complicada y no trae la suficiente tornillería para instalarlo.- El manual es casi inútil.- Seguro hecho de plástico. Con el uso siento que se podría dañar.
