Eliminate those ugly and often dangerous extension cords. You can add a new outlet quickly and easily without tearing open a wall, if you already have an electrical outlet in the other side of the wall. No extra holes. No messy patching and repainting. The procedure we show here allowed us to center our TV against a wall in the family room that had no outlet. Since there was already an electrical outlet in the other side of that same wall (facing into an adjacent bedroom), we just added a new outlet in the family room, drawing power from the bedroom outlet.
