Customer Reviews

KM 8 in. x 25 ft. HVAC Ducting- R8.0 is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from 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.
