OSP RS1U-SLIDER Universal Flat 1 Space Sliding Shelf

Smooth operation. Feels robust. Ventilated so you can lay it right on top of another unit or amp in your rack. Lots of travel. Feels like ball bearings in the sliders.

Installed easy. Slides better than a different brand that hand tightens onto the desk. Good buy

Nice for the money.

I’ve been using this product for a few months to store a laptop in my homelab. Sometimes I need to pull it out and open the lid or get access, so this is nice compared to a normal shelf. Customer service was very helpful when I had an installation issue. They didnt actually fix my issue, as the issue is with the design, but they tried to do what I asked with their own unit and called me back with their findings. My only issue with this is that you can’t install it with just 1u of space. It fits in 1u just fine, but you have to angle it into the rack to get the back ears inside the rails. If all you have is 1u, plan for a painful install. Once it’s installed, works great, though! Despite that issue I’m considering buying a second unit. For a homelab, it’s nice to have some more accessible shelves for a laptop, some rpis, nucs, etc.

I needed a pull-out tray for a small but surprisingly heavy appliance in my pantry. Cabinet makers weren't able to find anything suitable, but this pull-out shelf is a perfect fit for my existing cabinet. The dimensional drawings gave enough detail to make an informed purchasing decision, the adjustable rails work well, and it turns out, this was the only shelf on Amazon with these particular dimensions. So, I guess I got lucky that it fits perfectly after a minor adjustment to the rails. It might not be the sturdiest construction compared to some of the over-engineered 19" equipment that I have previously bought. But it is plenty strong to hold my appliance and then some. Most competing shelves are in the shape of an upside-down U. That makes them even stronger, but wastes an inch or two of space. I like that this particular shelf is very space efficient. Every inch counts when installing in a tight location. Finally, a surprising benefit of the adjustable rails was the fact that the mounting ears can be reconfigured to point out (as needed for installation into a 4-poster 19" rack) or in (as needed for installation onto a flat back wall. That made my work much easier. The only real downside was the packaging. It had all come loose by the time it was delivered. A flimsy piece of foam in a single-wall cardboard box is simply not enough for a heavy and bulky item. One of the mounting ears had deformed badly. But nothing that a pair of channel locks and gentle application of force couldn't fix. Whew. Good as new.

Slide mechanisms are very nice and smooth. It requires both front and back be mounted to be stable which I didn't pay attention to when I bought it; my fault. So I have to fabricate a way to utilize it on my audio desk but it's such high quality that I am considering it worth the effort rather than return it for something else.

Absolute garbage. The unit I received was slightly to wide to cleanly fit in my standard rack (I would add I have 2 identical racks, both loaded with an assortment of musical and computing/networking hardware that all fit perfectly). There were no instructions either so I had to figure out what kind of disassembly was required to finally get it mounted. Once mounted, it slid very poorly so I had to remove it to inspect the slides. It turns out the slides are made out of the cheapest and thinnest metal I’ve seen and were horrifically bent. I did the best I could to straighten the bends out and reinstalled. This time it failed to stop sliding within less than 5 uses. Given the size and hassle, I didn’t bother returning this junk. So I’m out the money I spent on this, which fortunately wasn’t that much. You get what you pay for I guess, so I’d advise anyone else to stay clear of this unit.

Nice sliding action with a bit of a "stop" to keep it from sliding out on its own. It took a little fiddling to get the rails positioned right so that the drawer is flush with the front of the rack and the rails extend far enough to the back, but once set up right it was simple to install. Sliding action is nice and smooth, it's great for easy access to whatever you need. If you want to use it with a keyboard, I'd suggest a TKL because the full-size keyboards with the number pads tend to be just a bit too wide to fit comfortably.
