Rated 5.0 out of 5.0 by This Is a very reasonable solution: This is a very reasonable and economical solution to my installation of flexible duct work. Now that a real solution is here I will be purchasing this often! December 14, 2011
Rated 5.0 out of 5.0 by What a value! I have been looking for this for years! I have been looking for this product for years. Quick and easy to install. Thanks for having this available to buy. My only complaint is I wish it was on your store shelves. December 14, 2011
Rated 5.0 out of 5.0 by Made rooms more comfortable in just a few minutes Straps over outside of flex duct to keep from kinking at bends. Just like a kinked garden hose, kinked flex duct keeps air from flowing. The kit comes with cable ties and easy to follow instructions. Only took a couple of minutes to install. If you have rooms with ceiling vents with low air flow, I would recommend looking in your attic for flex duct that has sharp bends and install this product. Would be nice to be able to pick this up at HD stores off the shelf with flex duct. December 16, 2011
Rated 5.0 out of 5.0 by THIS SOLVES THE BIGGEST PROBLEM WITH FLEX DUCT! My big issue with flex duct has always been air flow restrictions caused by tight bends and kinks. This product dummy proofs flex duct installations. Best thing about it is it fits any size of duct and any thickness of flex duct insulation. The cables ties that come in the kit go up to 10" duct size. You'll need bigger cables ties or put two ties together for bigger ducts. I like the fact it is made in America. This should be made to be code for all flex installs. December 17, 2011
Rated 5.0 out of 5.0 by Great concept that helps original intent Brian here, I have used this product for years and the concept of eliminating flow restrictions is brilliant. Easy to install with simple tie straps and one size fits many, nice. December 14, 2011
Rated 5.0 out of 5.0 IF YOU HAVE FLEX DUCT IN YOUR HOME - YOU NEED THESE Installed on sagging flex ducts in our attic. Went quicker after the first one. Found installation instructions easy to follow. Air flow at registers seem to be putting out more air now. Although this is not a product issue, it would have been more convenient to purchase these at my local HD with flex duct, almost gave four stars instead of five. December 28, 2011
Rated 5.0 out of 5.0 by This product will save you money! I gave this product five stars for the the fact that reducing airflow resistance (which is what this product does) saves money on utilities. It is super easy to install and saves energy. Great product! December 14, 2011
