This is a single piece accessory that can be used for custom Quiet Cool Fan installations where it is necessary to connect ducting from the ceiling box to the fan housing.
Some customer may require this ceiling box when there is an unsealed space between the ceiling and the roof/wall. This piece allows for a section of flexible ducting to be attached between the two units.
Ducting is sold separately.
Ceiling boxes may or may not be interchangeable due to differencess in ducting diameter depending on the model. Ceiling Box Accessory Piece |
