Well made and sizeable cable management system. Pretty easy to assemble and install. The cable tray attaches under the desk/table top with two bracket and associated screws. You'll need about 4 " - 6" clear from the back edge on the under side of the top to make this work. Has a metal plate in the bottom of the netting for setting a power strip.

Sturdy - Easily Adjustable - Works as Advertised

I modified it to fit a small subwoofer under my desk. I flipped the arms, inverted them and screwed it on to the desk. Not the intended use, but it solved my issue perfectly. It's really sturdy, it'll be perfect for mini PC's.

Flexibility and clean desk space!!!

Bought three of these for my home office. Two for Synology NAS drives and one for a Mac Studio. The size ranges make this the perfect product to get everything off my desk. A little difficult to install with the desk upright so I suggest turning it on its side or over completely. In my case, I have these in sit stand desks which is great.
