Form a trough into downspout while lining up
the edge of the score mark with inside of joist
creating a minimum of 1/4" per foot. Place
third staple through trough and downspout
on right joist. (3D)
»
Pull corner at ledger and right joist tight
keeping entire length of trough smooth and
wrinkle-free so as not to impede
