The "World's Fastest Hanger", the Clamp Hanger replaces the nuts and bolts that other hangers use with a genuine Nordfab® QF® clamp. Simply slide it into place and clamp it. Repositioning is no problem, simply unclamp the hanger, slide to the new position, and reclamp. We had this hanger tested at an independent test lab and it held up under stresses most ductwork will never experience. Our 9" hanger held up to 170 lbs and the 20" held up to 850 lbs!
