A flanged ring connector (50) for connecting adjacent ends of HVAC ducting (52) includes an insertion flange portion to engage within the interior of the ducting. A mating flange portion (56) extends laterally or transversely to the insertion flange portion (54). A seat (58) is formed along the mating flange portion (56) to receive and retain a seal (60) and/or a reinforcing member or bead (90).

A double wall round or oval duct system assembly having an outer duct connector, an inner duct connector and a closure ring is provided. The inner duct connector of the duct assembly has an adhesive applied on the transverse flange face of its transverse flange thus allowing a sealing connection between the inner and outer duct connectors upon compression with the closure ring. The double wall round or oval duct system assembly will improve the efficiency and will reduce or eliminate air leakage upon connection of two round or oval duct segments. A method of installing the assembly system is also provided.

A duct panel, a method of manufacturing a duct panel, a duct section and a method of installing a duct are disclosed. The duct panel includes a laminate structure having an insulation layer disposed between a first support layer and a second support layer, the laminate structure having an end width; and an end cap attached to the end width and configured to be coupled to a mounting flange, wherein the mounting flange is configured to mount the duct panel. The end cap and the mounting flange comprise different materials.

A carrier for seam formation and sealing comprising a roller assembly having at least one roller; a housing for holding the roller assembly; a fastening member for mounting the roller to the housing; and the fastening member is an interchangeable mechanism.

A flange to be assembled to a duct member includes a plurality of pre-fabricated apertures or areas of weakened wall strength for receiving fasteners to assemble the flange to the end of a duct member. The apertures may be spaced apart such that the fasteners can be inserted at regular intervals along the length of the flange and the length of the end of the duct member.

A stacked package of angle plates for use in association with a device for assembling individual ones of said angle plates into receptive flanges of HVAC duct sections is disclosed. A strap zone is defined as a portion of the stacked package located proximate to the apex of each of the angle plates, preferably from the apex to a point approximately 25% along the length of each of the legs. A single tensioned strap is placed extending around each of the angle plates in the stacked package and is located within the strap zone. The strap exerts a sufficient amount of tension to restrain each of the angle plates within the stacked package, and is preferably four foot-pounds.
