Product DescriptionDuro Dyne® 10003 Flexible Duct Connector, 3 in, Black, 24 ga
Product Features
All air duct installations for heating, cooling or ventilation are attached to mechanical equipment containing a fan or blower. Vibrations, noises and rattles resulting from the operation of the fan or blower are transmitted into the metal ducts which carry the noises throughout the system. In order to isolate the vibration and noises to the source, an air-tight flexible joint, consisting of a fabric which is secured to sheet metal on both sides, must be inserted between the equipment and the ductwork. This flexible joint is called a "flexible duct connector." To meet every type of installation requirement, whether it be for factory, institution, office or home; Duro Dyne® offers the widest variety of flexible duct connector fabrics (UL Listed) and sizes; pre-assembled with the sheet metal permanently secured to the fabric by means of exclusive seam locks. Duro Dyne® flexible duct connectors are dispensed from the carton, ready to complete fabrication faster, more efficiently and more economically than any conventional method.
