Ductmate 25/35/45 connection systems consist of roll-formed flanges, corner
pieces, gasket and cleat. The flanges attach to the duct wall and have an integral
mastic which allows the flange to seal itself to the duct. Corner pieces are used
to add rigidity to the flange; hold the ductwork together and provide a sealing
surface for the gasket. The gasket serves as a seal between the flanges. The cleat
insures even compression of the gasket along the length of the flange.
