Coleman Revolv white steel electric furnace door measures 19-5/8" x 50" x 1". Includes a 20 x 20 x 1 filter with clip. Vent opening measures 17" x 18".
Door fits Coleman electric EB Series furnaces with air conditioners up to 4 tons, including the EBxxB, EBxxC & EBxxD. For furnaces with air conditioners over 4 tons, order door 3501-9311 as it has a bigger vent area.
Filters can be purchased at most hardware stores. Purchase only regular filters, nothing too dense or fancy as they restrict airflow too much and will shorten the life of the motor or trip limit switches. Filters will fit tight. Sometimes trimming off one edge will help them fit better.
