This is the KwiKool DCR-12, a 12-inch duct flange for the condenser side of KwiKool portable air conditioners, giving the discharge duct a rigid collar to clamp onto.
It finishes a portable-cooling install where the hot air has to leave the room cleanly — through a ceiling panel, wall plate, or window blank — with the duct seated on a real flange instead of tape.
KwiKool has manufactured portable cooling systems in Houston, Texas since 1997, building each unit from high-grade steel and predominantly American-made components.
