Better drafts are produced by a taller chimney. Unfortunately, it can be challenging to locate chimneys and flues that were constructed with the correct dimensions and height to offer the best ventilation. To move the top of the flue into a new airflow and restore the right draft of the chimney, a flue extension can be necessary.

Installs on chimney where no flue is extending or flue is too short; Tapcon screws are included.
