Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Flex Duct First Timer I used to add supply and return to attic bedroom. Easy to use, cut and install. Outer jacket was tough enough that I didn't worry about assembly outside the knee wall and dragging through the access door. After reading all about the draw backs of flex duct I did use ridge wall connectors at ends and any turns. Final result air flow is excellent to attic. September 30, 2014
