Abstract: An adaptor for eavestrough downspouts has two portions of different cross sections. The first section fits outside the downspout and the other fits inside the drainage extensions. The two portions are hinged together. The adaptor is formed with step-down sized cross sections and a removable panel to allow more sizes of downspouts and extensions to be connected.

Abstract: An adaptor for connecting industry standard eavestrough downspouts to drainage extensions of a similar or dissimilar cross section and allowing the extension to be pivoted vertically. Such an adaptor is shown with portions having two different cross sections, one capable of fitting outside several industry standard drainage extensions and having a hinge between the two portions. A mating Velcro.TM. loop-and-hook pair is installed on the drainage extension's outer end and at an appropriate place up the downspout. Thus, a downspout with a round, or squared, or rectangular cross section can be connected to an extension with any of these cross sections, making a total of nine permutations and more if minor bending or fitting of further sizes and shapes of downspouts or extensions is undertaken. In the preferred embodiment, the extension can thereafter be raised to a vertical position and separably fastened there.
