Duct Markers & Labels

The duct markers at Hansen Supply help identify air duct contents and flow direction according to ASME (ANSI) standards. These ductwork identification labels are color-coded to differentiate between hot, cold, and specialty ducts. Our duct labels also come with detachable arrows to accommodate different airflow directions. These adhesive markers are especially important to display before ducts enter a concealed and in intervals of 50ft.
