The Supurr-Flex duct is for dyer venting but is also suitable for bathroom venting, HVAC systems and general-purpose venting. The 5-ply all-aluminium constriction offers superior fire suppression. The flexible duct is easy to install and can easily be cut to the length of the specific venting application. Use with gas or electric clothes dryers, fresh air intake or other non-insulated duct installations. Includes two plastic clamps.
