Nice for cable management
Real metal so it is very sturdy and if you tighten your screw it will be very stable too. I out it next to my monitor mount which provide a nice setup for cable management. It fits perfectly to a VESA 100x100 mount. I have a similar setup in my office but under the desk which makes it versatile.

Fits HP G2 dock
I have this mounting an HP-G2 Dock on the back of my Samsung 28inch 4K monitor. I used an additional flat plate to mount this to the left with the monitor arm going the plate and into the monitor. So good I bought a second one for my co worker so our desk don't have wires on them now.
