These were the best thing I did when we had to remodel and I added a large built in countertop. They are made well, and easy to install! They are very versatile since they are designed with both USB-A and USB-C ports along with the standard 110V plugs. I use these with my 3-D printers, laser engravers, computers, printers, and even a few coffee pots!

No issues, and no instructions.

Style: 20W_USB-C, Size: 6FT

No, you don’t need instructions, because the hole dimensions are in one of the photos. 4” x 1.73” is perfect. Plug it in and all of the ports in both that we bought worked perfectly.

Multiple ports

The usb outlet broke within a week of purchase. The rest of the outlets work perfectly. Like that it has multiple ports to plug in.

Thank you VIVO

Between these cable management trays and the VIVO under desk UPS mount, I have completely tamed the cables at my desk. No more tangling my feet in cables when I stretch. No more messy, unkept appearance. Even with zip ties, I was never able to get anything close to this. It's truly amazing what the right hardware and a little bit of work can do. Everything you need is in the box. I do recommend drilling pilot holes, even in particle board or softer wood to make it easier to screw in, but the installation is dead simple and done right, no one will even know these trays are there. I should have done this years ago.
