HP G5 Dock Mount
Works as advertised! I purchased this as a test piece for our office supplied computers. It frees up space in the desk nd hides unsightly cords from view. I have it wall mounted behind the monitors and am very pleased thus far!

Necessity
After the disorganization of my working space drove me crazy, I did an overhaul. This was one of the additions that I bought to not only give me more space but also allow for better cable management. I mounted mine under my desk, which let me contain the cable chaos beneath the desk.

Fits great.
Multiple iterations of this dock have wires coming out both the front and back, making it ugly on the desk and no way to hide wires well. Mounting under the desk with this helped a ton, looks way better. Perfect fit.

Highly recommended and easy to install and use
Color: Black, Size: Standard
Perfect for creating a “compartment” under your workstation to organize and gather wires. Product feels solid and is well finished - NOT flimsy at all. Smooth surfaces with no metallic buts whatsoever. Easy to install with even just a screwdriver and some old fashioned manual work. I skipped the drill. The supplied screws are self tapping. Product installs fast and is unobtrusive. Minimalist design. Happy with purchase.

Amazing product!
Color: White, Size: Standard, Color: White, Size: Standard
I love this item so much, it makes my wires super organized and it holds them well. The white appearance goes cleanly with my white desk frame, and the size is perfect to fit a lot of wires. It has amazing functionality and comes with 2 screws. I do recommend pre drilling holes so you do not ruin your desk, and ensure that your desk is thick enough that the screws won’t pierce through.
