About this item Completely Dressed Port System - No chasing wires down inside the walls! This is a single, two-piece unit. The pictures with the multiple sizes are to demonstrate the variety of sizes these units are available in. 'A hole in the wall never looked so good!' 'Take it to the other side!' This unit puts a hole from one side of your wall to the other through a neatly dressed port. It does not allow access to the area of the wall where the studs lie. It simply allows the running of cables from one side of a wall to the other. Dimensions: 5.25 x 2.5 x 2.5 inches.
