Claim 9:
10. A method of using a flexible duct comprising:
providing a flexible duct including
a hollow tube shape;
at least one end;
a first circumferential attachment integral to the at least one end;
a second circumferential attachment integral to the at least one end,
wherein the first circumferential attachment and the second circumferential attachment are different,
wherein the at least one end has a first configuration in which the first circumferential attachment integral to the at least one end is positioned to independently mechanically couple the at least one end around a first inlet or a first outlet and a second configuration in which the second circumferential attachment integral to the at least one end is positioned to independently mechanically couple the at least one end around the first inlet or the first outlet, and
wherein the first configuration and the second configuration are different;

selecting one of the first circumferential attachment or the second circumferential attachment; and
mechanically coupling the selected first circumferential attachment or second circumferential attachment around the first inlet or first outlet.
