ABSTRACT:
An adjustable extension assembly for a downspout includes a fixed piece attachable to the lowermost end of a downpipe, a rotatable collar attached to the fixed piece, and at least one extension pivotably attached to the rotatable collar. Optionally additional slidably extendable members may be telescopingly attached to the extension. The extension members are channel-shaped in cross-section. The extension may be composed of a polymerized material or a metal. In addition to being easily attached to a downspout, the adjustable extension of the present invention may be selectively adjusted for fitting, for selective water deflection, and for proper lawn maintenance.
