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.
