An air distribution apparatus can include an air distribution housing with an outer wall and an interior area. If provided with a housing, the air distribution apparatus further includes a duct that can be pivotally connected do the housing and configured to pivot about an axis from a retracted position to an extended position. A portion of the duct can be received in the interior area of the housing in t he retracted position and the portion of the duct can extend outside of the interior area in the extended position. In further examples, the air distribution apparatus can comprise an adapter configured to be attached with respect to an opening of an air distribution housing. A duct can be pivotally connected to the adapter and configured to pivot about an axis from a retracted position to an extended position with respect to the adapter.
