The ABCDWH06 is designed to be installed over a 6-in diameter hole in the ceiling. A galvanized duct boot would be required to be installed above the ceiling to fasten the flexible duct work. Please note that this item does not have a damper. If you need a damper as well, please look for model # ABCDBRD06, which is designed to work with this item. If you have any other questions, please call our Customer Service team at 877-531-7470 and we will be more than happy to help you.
