Rated 3 out of 5 by 2 reviewers.
Rated 2 out of 5 by Distorted I ordered ten half-sections of 8"x16" to make a 20' trunk line and found that the material was inaccurately bent and it was impossible to make a straight duct assembly. When assembled with drive and S-cleats, the resulting assembly was twisted and could not be made straight, since some key bends and at least one bend allowance was incorrect. The final assembly was ugly and very disappointing. I would have returned the material if not for time constraints and I will not be using this product again. October 21, 2014
Rated 4 out of 5 by Price each The duct saves time and labor but when doing price shopping on the site you might want to know the price is per section not for both sections. October 17, 2010
