Review on SE AtlasDesign Double TV socket + computer RJ45, cat. 5E, ATN000189, white by Wiktor Wiater ᠌

From experience I will say that it does NOT fit other frames, including w59 and w59 deco (you can install it on 59, it will hold on, but it will also stand out strongly) it is better to put it on the original naturally. They are installed quite simply, first one part of the Internet is separated from the common support and separately both parts of the TV and the Internet are connected to their wires.
