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?

Answer: 
Thank you for contacting MasterFlow ... The nylon strapping does not come with this product. Look for items 3/4 HS (Metal Hanger Strap) or HS1.75 WW (Woven Hanger Strap). They are available at your local Home Depot Store. Please call Technical Services at 800-211-9612 with any additional questions.

Rated 4.0 out of 5.0 by What you would expect Easy to use and appears to be a quality product, time will tells how good of a product it is. August 29, 2014
Rated 5.0 out of 5.0 by 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. November 12, 2013
Rated 5.0 out of 5.0 by 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. May 29, 2012
Rated 5.0 out of 5.0 by Works as intended Tuff, sturdy outer lining. The insulation is very thick and does a great job delivering heated air. January 2, 2012
