This is our show-piece install. It shows pictures of the different stages.
Our Show Piece Installation
Firstly, out came the plaster and in went the trunking to hold the cables. When the trunking was fitted the cables were then routed inside.

Then, in went a rough plaster repair / cement power mixture to cover the conduit. Also the steel bolts were cemented into the wall and the bracket attached.

As you can see the cable outlets were given a plastic edging to finish them off.

The pictures below show the install 2 days later when the final skim of plaster had gone on and the wall paper was put up. (Note: this stage was not done by us.)
We returned to mount the TV and tune all the other equipment.
