ABSTRACT:
A first section of cylindrical sheet metal duct has a end roll-formed to define an outwardly formed flange, a central cylindrical flange whose axis is parallel to the cylindrical wall of the duct and which is radially outwardly offset from the cylindrical wall, and an inwardly formed end flange. This configuration defines a male section and the end of a mating section of cylindrical duct is formed to define a female section having an outwardly formed flange extending from the cylindrical wall and a cylindrical end flange whose axis is parallel to the cylindrical wall and radially outwardly offset from the cylindrical wall with a diameter slightly greater than the diameter of the corresponding cylindrically offset flange of the male section such that the male section can extend into and be seatably received by the female section. A band circumscribes and overlies the junction of the male and female ends of the ductwork and includes an adjustable clamp for tensioning the band thereby securing the sections together.
