Got Some Work To Do!
Color: Black, Style: Adjustable Width
Inspired by a kitten, I endeavored to clean up behind my audio desk, where a maze of wires is the picture of confusion, but apparently also a wonderful place to pull and tug, nap and chew ... so I got this. Then it sat there for a week while I thought about it. Felt complicated, organizing that big wad of a mess of wires. But when I finally got to it, it wasn't too bad at all, and the difference is huge! This item fit under the back of the desk perfectly and provides a deep tray you can immediately start to run wires though. Eventually you'll get there! Good luck!

Solid and strong
Color: Black, Style: Fixed Width
It's strong enough to hold it's shape. I attached it with 2 screws, and was able to put 2 power strips inside. It's a bit annoying to have the big "StarTech.COM" logo on the front, so I mounted it backwards, facing the wall. The whole point of a black tray is to hide things and blend in, not advertise for "StarTech"! So minus 1 star for that.
