Hi! This Metal-Fab 8TGRS 8" does support 20 feet of pipe - not 20 pounds. It will support up to 20' of 8" TempGuard. For reference, 1-8" diameter, 48" length piece of TempGuard weighs 21 lbs. We hope this helps. If you're interested in purchasing the Metal-Fab 8TGRS 8", click the "Add to Cart" button, enter your zip code and you'll be all set. Thank you for visiting PlumbersStock.com. Have a great day!
