Abstract
A wall entry tunnel for use with a pet door. The wall entry tunnel extends through a structural feature and forms an enclosed passageway connecting the interior and exterior frames of a pet door. The length of the wall entry tunnel adjusts to fit structural features of various thicknesses. The wall entry tunnel includes modular components that facilitate compact packaging and are readily assembled to construct the enclosed passageway with a perimeter sized to match the size of the pet door opening.
