50 feet Lite Weight Black Nylon Duct Support Webbing Strap Belt 1-3/4" 1.75"

After we had work done on the crawl space adjacent to our basement, some of the flexible ductwork was left hanging like giant, wet spaghetti. After salvaging whatever nylon straps weren't completely cut to pieces, I purchased this role of light weight straps to finish the job. They helped me get my HVAC ducts back in place as expected.
