4" x 8" Fire Box Air Inlet Slide Damper Kit

Easy installation, simply cut the required size hole in your firebox and install this kit by stitch welding it over the hole.

Newly redesigned 4 x 8 slide damper, reduces cost and increases airflow over our previous 3x10 damper assembly. Additionally it reduces the width substantially for use on smaller fire boxes.   32 sq in of intake air.  Outside dimensions will be approximately 18" wide and 7-3/8" tall.  Heavy duty 1/4" plate steel slide damper with pre-bent 16 ga housing.
