Model A100 A-Seam Stretch-Fit Thermofin® Air Duct is a semi-rigid flexible aluminum pipe UL® 181 Class 0 used as supply, return or exhaust. It solves the need for an easily bent duct which makes small radius elbows. Our factory crimp ensures smooth connections.
New for 2022: A-Seam tighter compression
This patent pending design allows for tighter compression without making it harder to pull it back out for installation.
• T-Fin® design allows for better stretching and bending characteristics which helps eliminate flattening on the outside radius of a bend, thus preventing restricted airflow.
