An exploded 3D view shows the installation sequence of a through-wall scupper and downspout conductor head assembly. The scupper sleeve insert is surrounded by compressible foam joint filler and supported by fire-retardant treated wood blocking. Metal counterflashing is sealed along the top and sides, while the scupper face plate is fastened across the bottom flange. The downspout conductor head slides in behind the counterflashing and face plate, connecting directly to the downspout below.
