Perfect Solution for Desk Cable Clutter!
Color: White, Size: Standard
I’m super happy with the VIVO 2-pack under-desk cable management trays. They’re exactly what I needed to keep my workspace clean and organized. The 17-inch size is perfect for holding power strips, chargers, and all those messy cords that usually clutter up my desk area.
Installation was a breeze — the trays come with all the screws and clear instructions. I mounted them under my desk in just a few minutes, and they feel really sturdy and well-built. The metal construction looks sleek and durable, and it holds everything without any sagging or bending.
Now my cables are off the floor and totally hidden, which not only looks great but also makes cleaning so much easier. If you’re tired of tangled cords and want a neat setup, these trays are a must-have!
Highly recommend!

Perfect cable management
Color: Black, Size: Standard
I set these up on my sit/stand office/gaming desk and trust me when I say I have a lot of cords, power blocks and what not going on. 2 27" monitors (both have DP and HDMI hooked up), two laptops, PS5, gaming speakers, iPad, docking station, phone charging station...and this thing holds all of the cables, blocks AND the Anker multi-plug with 12 outlets. No cords hanging, everything clean. Super easy to install, I totally recommend this product. I like it so much I bought another one for my girlfriend for her home office to get her all set up. You won't regret it

Use Velcro or Command strips and save yourself money
Color: Black, Size: Standard
These are high quality and are nice additions for the VIVO standing desks. However, they only fit slim power strips. My power strips were too wide to fit these. I ended up just using Velcro and Command strips to attach the power strip under my desk and purchasing cable management wires. In the end, I think it turned out much better than using these cable management trays and also saved me a significant amount of money.

Works for hiding cables
Color: Black, Size: Standard
Worked great to manage my cables to my pc setup. My double wide surge protector fit in there just right. Easy to mount with the holes and the bottom to fit a screw driver or power drill. Not too flimsy.
