The round downspout is superior in transporting water from the gutter and out. Just ask any plumber why we all use round piping, it is simply the most efficient way of transporting fluids. Constructed from the same strong 23 gauge galvanized steel as the gutters, the double interlocking seam is super strong and the preshrunk end, overlaps 2" perfectly every time. Each downspout is 10' long.
