Doses were laid with CAT7 cables. The lateral introduction of even 2 lines requires some strength and skill in the introduction to land flush-mounted socket. However, some wall outlets bothered a metallic nose to the wall outlets that I pinched off with a wire cutter. The cable connectors can be fixed with a good punch down (LSA from Ligawo). It should be noted that the cable ends do not touch the metal housing. The cans carry color samples for the cable connectors in the A and B version. I have the B solution consistently used the patch panel where the other cable ends have been merged. The data outlets I fixed with 2 screws to the wall outlets. That went smoothly and provides secure attachment. Unfortunately, the screws are not included. It would be nice if an assignment to the sockets (left / right) would be marked out on the cable connections.
