Nice and sturdy.
Color: Black*2Pack
This system worked for what I needed. The metal wire trays are well-made and big enough to handle larger power strips. I was concerned when ordering it, as I have had to return several in the past, from other companies that were just too small. These, along with the wire holders, made channeling the wires behind my desk rather easy.

These worked out well
Color: Black*2Pack
These worked out well. One of the two baskets was bent a little so I had to adjust to make them match. The baskets are strong and they are holding multiple power supplies without issues. I don't prefer self tapping screws but I pre-drilled small pilot holes and they worked fine.

Racking Solution for Networking Devices
Color: White*2Pack, Color: White*2Pack
Guess I need to clean that wall...
It's not noticeable in person but really came out in these pics lol
THE REVIEW
I bought these because I wanted to clean up and my networking setup.
I refuse to get an all-in-one device from my cable provider, opting instead to purchase my own modem, router (Netgate), switch, and access point (Unifi Cube).
This ends as spaghetti and meatballs setup of cables and devices. Nothing beats a racking system for isolating components, protecting them, airflow for cooling, etc.
I've attached a couple of pics of the setup. From ground up, you go through modem, router, 10-port managed switch, and out to wifi access point and secondary 5-port switch that are in other rooms.
I wanted something that would:
- Get these off of the desk level in case of another coffee spill ;-)
- Separate them enough to where they can breath without sucking up heat from one another
- Keep cables neat/organized
This turned out to be a very inexpensive and perfect solution.

Keep my cables very organized. The size is perfect to fit the battery of my stand table and cables. Very easy to install. Great product for the money you pay.
