Abstract
An end tube has an interior and exterior diameter and a length. A central tube has an interior and an exterior diameter and a length. The length of the central tube is greater than the length of the end tube. The exterior diameter of the end tube is essentially equal to the interior diameter of the central tube. An upper portion of the end tube is inserted into and attached to a lower portion of the central tube. In this manner a lower portion of the end tube is adapted to be inserted into a vent pipe of a roof.
