A standard pattress box or conventional face box rounds off a cable entrance neatly and tidily.
The other option is a simple bung thet slides over the cable going into the wall making the entrance neat and acceptable.
Patress boxes can be sunk into the wall,so matching the other sockets,this is a lot of work,requiring in some cases chiselling out the brick to get the depth for the back box.
Plasterboard make sit much eassier,you just cut teh hole and clip th ebox in.
Most tv aerail face plates are simple whit finish,but we can provide a range of finishes,chrome brass etc etc just enquire.
