This 2 1/2" ID Premium Flapped Unit - Fits Barrier Thickness between 4" - 6". This unit is equipped with a rubber end that provides a much more closed end as compared to our standard units, both when in use and when not it use. This unit, like most of our Wall Eye Ports provide a fully tubed hole through a barrier, such as a wall. This port seals off the opening from the inside of the wall, while allowing cords, tubes and wires to be passed through the opening easily, while maintaining a aesthetically pleasing look.
