Deflecto ATOSB44 is an Airtight oval-to-round duct connector designed to join a 4 in round dryer duct to an oval in-wall duct. Constructed of aluminum for metal-to-metal connection, the adapter provides higher heat resistance than plastic connectors and can be disconnected for cleaning. Deflecto Airtight technology reduces leakage and improves appliance efficiency for dryer venting and HVAC transitions.
