150mm x 3m Semi Rigid Aluminium Duct

The 150mm x 3m Semi Rigid Aluminium Duct is a length of semi-rigid aluminium duct, used for short, exposed duct runs where a rigid, self-supporting duct is preferred over flexible ducting. Its semi-rigid aluminium construction holds its shape better than flexible duct, giving smoother airflow and a tidier finish where the duct is visible.
