Solid quality and does what you expect
Color: Black, Size: Standard
Nothing revolutionary but it's exactly what you expect. A sleek metal cable tray that you easily screw into the bottom of your desk

Sleek, Sturdy, and Matches My Desk Brand Perfectly
Color: Black, Size: Standard
Great on-brand cable management tool. Honestly, I only bought it to match my desk brand—cable management is cable management—but I’m really glad I did. It looks solid, feels high-quality, and the metal construction adds a nice sleek touch under the desk. Clean, minimal, and functional.

Works great, easy to install.
Color: Black, Size: Standard
Does exactly what it’s supposed to do and comes with screws. Installation was easy once I drilled pilot holes and used a screwdriver. The only downside is that a longer drill bit would have made the process easier, but that was on me for not checking beforehand.

Simple solution for a cleaner desk
Color: Black, Size: Standard
This cable management tray made a big difference in cleaning up the mess of cords under my desk. It’s sturdy, easy to install, and holds a power strip and extra cables without any problem. Once everything was in the tray, the area under the desk looked much more organized.
