Abstract: The Downspout Extension Ground Support supports a downspout extension at grade level. In instances where downspouts need to be extended from a structure, the Downspout Extension Ground Support provides support and stability to maintain the correct pitch for drainage to flow through the downspout extension as designed. Without support under the downspout extension it will tend to sag, disrupting the pitch which in turn impedes proper drainage flow; and in some cases causes backflow.
