does this come with the cable ties to connet to the duct?

The old one on my furnace now has heavy duty cable ties holding it secure to the duct. I want to know if the cable straps come with it or do you have to buy something else to attach it to the existing duct?
Asked by: Taffy88
No, ties not included. My old one didn't have ties but I put a couple on anyhow -- probably wouldn't be necessary if you use a quality metal tape to secure and seal.

Rated 5 out of 5 by from Easy to work with I bought this to replace the failed flex duct (different brand) in my mobile home. It was easy to cut and pull back the vapor barrier and insulation to install. Very easy to work with and has a good quality vapor barrier. Hope this helps.

Rated 5 out of 5 by from good qua;ity product My mobile home is 20 years old and the HVAC 12" ducting outer jacket was perforated and the insulation exposed and falling out. My installer commented how obvious this product appears and feels much more durable and substantial than the original. Along with replacing some of the insulation around the connecting ductwork, it has made a significant difference. It takes a lot less time for my furnace too reach set point. Well worth the money.

The heating "expert" said it would cost $1000, parts alone would be $700. We were able to get this and repair it ourselves for $50.
