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.
