ABSTRACT:
A portable air duct extension for a building heated or cooled by air and having a hot or cold air outlet or register. The duct extension comprises an elongated tubular member composed of telescoping sections. One section has an inlet opening and the other section has an outlet opening. Means such as magnets are provided for removably mounting the tubular member so that its intake opening overlies the air outlet. The telescoping sections permit the tubular member to be adjusted as to length to vary the point of discharge through the outlet opening. Baffles are provided to control the discharge of air from the outlet opening.
