ABSTRACT:
A repositionable downspout extension is formed as an integral blow molded plastic component having three distinct sections. A downspout connector end merges with a corrugated extendible middle section which terminates in a drainage pipe connector. The downspout connector includes two rectangular sections of different sizes defining two different securing segments for engaging two different sizes of downspouts. The middle section is of a pleated configuration and is of variable length by expanding or collapsing of the pleats. The drainage pipe connector is a circular connector for connecting with commonly used corrugated plastic pipe or rigid plastic pipe. In a preferred embodiment the downspout connector end also includes a connector for insertion and retention in the corrugated middle section.
