A wire trough includes a body having back walls that engage the surfaces of a wall and a ceiling in a room. Side walls extend from the back walls to provide a horizontal and a vertical surface for stubbing in conduits. The trough also includes a cover that is used to permit access to an interior space in the wire trough. Multiple troughs may be assembled together to extend the length of the trough. Conduits may also be stubbed into the ends of the trough.
