Patent ID: 7410416

Claim:
A system for distribution of air from a central air unit to multiple distribution points using complimentary components comprising: (a) a boot having a unitary body defining an air pathway between a first and a second opening, wherein the first opening is substantially circular and the second opening is substantially rectangle for connection to a register, the unitary body further comprises a first collar of a first diameter operatively connected to a second collar of a second diameter defining the first opening, the first diameter being greater then the second diameter, the first and the second collar further comprising a first rib on the first collar and a second rib on the second collar for connecting to a pipe; (b) a pipe having a unitary body defining an air pathway between a first and a second opening, wherein both the first and the second opening are substantially circular for connection to a boot or a takeoff, the unitary body having a first diameter operatively connected to a collar of a second diameter defining the first and the second opening, the second diameter being greater then the first diameter; (c) a takeoff having a unitary body defining an air pathway between a first and a second opening, wherein the first opening is substantially circular for connection to a duct and the second opening is substantially circular for connection to a pipe, the unitary body further comprises a first collar of a first diameter operatively connected to a second collar of a second diameter defining the second opening, the first diameter being greater then the second diameter; (d) a duct having a rectangular body, a length, a first and a second connecting edge and a raised flange along the length of the first connecting edge, a set of scorings spaced apart and running parallel the length of the body, a first and a second opening formed by folding the body along the scorings and overlapping the raised flange and the second connecting edge, the rectangular body defining an air pathway between the first and the second opening wherein the first and the second opening are substantially rectangular for connection to a central unit, an end cap or a duct; and (e) an end cap having a rectangular surface supported peripherally by an edge and a wall, the wall extending perpendicularly and outwardly from the rectangular surface for closing off the end of a duct.
