Examine the route of the cable raceway. Plan a route from where the cables start and where they end. Cable raceways usually run along the ceiling, on the edge next to a wall, thus minimizing their impact on the aesthetics of the room. However, it can also be run along the floor.
Attach the first section of plastic piping to the wall. Use clamps to secure the piping into the wall. Piping usually comes in 1- to 3-foot sections. Select an appropriate length. The piping is built to have another end insert into it.
Pull the cables through the first section. Pull the cables through the second section of piping and attach it. Insert the second section of piping into the first, and attach it to the wall or ceiling by screwing in clamps.
Repeat Step 3 for additional sections of piping. Always pull the cables through the piping as you go. For corners, use an elbow bracket. Do this until you reach your final destination.
Paint the piping if necessary.
