Customer Reviews

Rated 2.0 out of 5 by 1 reviewer.
Rated 2.0 out of 5.0 by Spliced Run Like any other flexible duct it was easy to install. I was a little disappointed that the inner core teared easily and very disappointed when I noticed that the inner core was not a continuous 25ft run. When cutting it down to size I ran into a splice. It was put together with 3 metal clips and a lot of clear tape. Couldn't believe my eyes. I installed 11 runs in total, 7 full 25ft. runs and 4 sized. By the quality of the inner core, I image I will need to replace them all within 10 years. My original ducts were 20 years plus. May 2, 2015
