This assembly consists of a 24-gauge galvanized iron overflow and scupper unit mounted to the wall panel, featuring both open-top and closed-top configurations as indicated per the roof plan. The unit includes internal galvanized iron supports and is positioned relative to the top of the roof deck. A 24-gauge galvanized iron downspout connects to the drain outlet, with all exposed metal components painted to match the building exterior. The assembly is dimensioned with specific clearances and widths, including a 4-inch separation between the overflow and drain sections, and is aligned with the building's panel joint layout.
