Two kind of support are uploaded. One is like a basket where you could put your wifi router or a raspberry PI or a micro computer as well. The other one is a frame to screw things like a plug slipper. Both of them use the same way to hook to the tv support, and is by press a the metal sheet. This metal sheet must be as 2 mm of thickness. Designed for TP-Link n750 or Archer C7. Maybe you could use on other equipment since its measurements are standard and it have holes to grip it.
