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. 575 "quick seal" -
square to round takeoff with self-adhesive flange. Meets
SMACNA specifications. See Page 12. |
