the second structure disposed with its first side adjacent the second side of the lower cabinet and with the raceway of the second structure opening through the first side of the second structure and through the second side of the lower cabinet into the front raceway of the stacked cabinet structure to permit laying in of utility wire across the entire combined width of the stacked cabinet structure and the second structure.

5. The stacked cabinet structure as claimed in claim 3 in combination with a second cabinet structure substantially identical to the stacked cabinet structure,

the stacked cabinet structure and the second cabinet structure disposed with a second side of the stacked cabinet structure adjacent a first side of the second cabinet structure and with the front raceway of the stacked cabinet structure opening into a front raceway of the second cabinet structure to permit laying in of utility wire across an entire combined width of the stacked cabinet structure and the second cabinet structure from a position forward of the front access opening of the stacked cabinet structure and a front access opening of the second cabinet structure rearwardly to a position in the front raceway of the stacked cabinet structure and the front raceway of the second cabinet structure.

6. The stacked cabinet structure as claimed in claim 1 wherein the front raceway is open at least one side of the compartment for passage of utility wiring into or out of the compartment, and the rear raceway is open at least one side of the compartment for passage of utility wiring into or out of the compartment.

7. The stacked cabinet structure as claimed in claim 1 wherein

the compartment is open at a side access opening at each side of the compartment with each side access opening opening forwardly into the front access opening and rearwardly into the rear access opening,

the front raceway is open through both sides of the compartment via the side access opening for passage of utility wiring into or out of the compartment and to permit laying in of utility wire across the entire width of the stacked cabinet structure from a position forward of the front access opening rearwardly to a position in the front raceway,

the rear raceway is open through both sides of the compartment via the side access opening for passage of utility wiring into or out of the compartment and to permit laying in of utility wire across the entire width of the stacked cabinet structure from a position rearward of the front access opening forwardly to a position in the rear raceway.
