I crashed the trough with a car and damaged it. I did not hit nearby home centers and building material shops, but it seemed that it took me a while to treat it as a sheet metal dealer. Since I wanted to repair it by rainy we had a PC search for "Monotaro" that I used before, there are descriptions of part number, color, etc. I found an alternative item and ordered it. The goods arrived immediately by delicious packing and completed construction on their own without rain. Thank you.
