StarTech.com 1U 4-Post Adjustable Server Rack Mount Shelf - 330lbs(150 kg) - 19.5 to 38in Adjustable Mounting Depth Universal Tray for 19" AV, Data & Network Equipment Rack - 27.5in Deep (ADJSHELFHD)

I bought this for a 24" deep server rack, to hold a Sony VGP-XL1B 200-disc changer, which weighs about 38 pounds empty and has a huge footprint, at 17" wide, 21" deep, and over 7" tall. This was the most affordable option with a high enough weight capacity to be certain the changer will be secure and stable when full of 200 discs.It was easy enough to install, although the side posts of my rack got in the way, and it took a little finangling. We ended up installing the front brackets in the rack and the rear brackets on the shelf. Sliding the shelf into the front brackets allowed us to ensure everything lined up for screwdriver access through the square holes on the side posts.This shelf is a bit deeper than the rack, but this works out pretty well, since it leaves space in front of the changer for placing CD and DVD cases while loading.I'm happy with my purchase. I wish it were a bit cheaper, but I also understand that a solid shelf like this uses more raw materials and costs more to ship, so I think the price is probably fair enough.

Very heavy duty, went together really easy. Happy with the purchase wish it was a little cheaper price. Gets the job done

Just like another review mentioned, it is a pain to install on an existing rack. Fortunately for me I did not give up and after an hour, I managed to get it installed. What made it harder was that this was for the lowest part of my rack.I only bought it since my rack is also by StarTech, but I'm not sure, like another reviewer mentioned, it's worth $100. The build quality is there, which will definitely be hard to find if you were to go with a cheaper alternative.I'm considering purchasing another for the upper portion of my rack, but it also is slightly too deep. Just a few inches. Not a huge problem given that I can still close my closet door.

The 175-pound version of this shelf arrived well packaged in double boxes.The shelf is very sturdy and has flexible mounting options. I was able to install the shelf myself; however, having two people would make the install faster and easier.Detailed specifications for this rack can be found on StarTech’s website.

I own 4 and let me tell you these are sturdy. My servers have 15+ hard drives each and these hold them fine.

This is a must have item for any server rack. It takes time to install and adjust to the correct length. Once it's installed it is very sturdy.

It's a shelf. It's currently holding two UPSs in my rack. So, I can say it does its job as one would expect. The included cage nuts/screws were nice to see.I've installed a lot of IT gear over the course of my career, and I guess I never knew how "easy" I had it bc this thing was just a chore and a half to properly install. It costs far too much for what it is and for what it takes to install it. It's just folded steel with slots, holes and extremely basic brackets...

Very solid shelf used at the bottom of my 4 post media rack. Adjustable length very useful to ensure the shelf woudl fit my application. Construction is very high quality and confident that it will have no issues holding the rated weight. Mine is currently holding a ~80lb 3 channel amp.
