Champion makes several fittings that can be used for commercial applications. 652, 653, 654, 664, 665 "spin in" fittings used for takeoffs in metal duct work. After the proper size hole is cut, a slit is made perpendicular to the perimeter of the hole which mates with a similar slit in the fitting flange. This allows the fitting to be twisted into the hole in the metal duct. See page 11. 581 "quick seal" - square to round takeoff with self-adhesive flange. Meets SMACNA specifications. See Page 12.
