Downspout

I had the option of NOT putting a downspout here because the gutter is open at the other end (at the L corner). It flows into the lower gutter which leads to a downspout at the far end. However, because of the significant tributary roof area from this side, I decided to take the hit in visual appearance and just be safe.

It's made from a standard 2"x3" smooth profile that comes in galvanized metal. A single piece was angle-spliced at the bends and riveted into shape. The important thing is to always lap the top section inside the lower cut. Flashing sealant was hardly necessary, but applied anyway. Metal primer helps. Only two fasteners were necessary at the post -- also riveted for a seamless finish.
