I'm about to mount a TV on the wall and have some trunking 100 x 50 to hide the cables. I want to sink the trunking into the wall but am conserned about the depth. Its going on the party wall of a terraced house and would be about 1m vertical. I assume the wall is double skinned brick but not sure yet. Would the 50 mm depth be safe or should I keep it to 25mm? Could I keep to the 50mm if I put a concrete lintel above the chase?
Thanks
Paul
