Dundas Jafine Round to Oval Plastic Dryer Duct Connector is designed to seamlessly connect in-wall oval shaped ducting to round shaped dryer transition ducts. Crafted from high impact polystyrene, this durable adapter features a built-in threading system that allows for a quick and secure connection to flexible aluminum foil or semi-rigid aluminum dryer ducts without the need for clamps or duct tape. Included with the adapter is a 4-inch galvanized steel worm drive clamp to firmly secure the in-wall oval duct to the connector. Its easy installation makes it compatible with any recessed dryer vent box and helps save valuable space in your laundry room by enabling the dryer to be pushed back against the wall. Additionally, this adapter can be easily disconnected for routine cleaning of the dryer duct, ensuring efficient dryer operation and safety.
