This architectural drawing is Scupper detail in AutoCAD 2D drawing, dwg file, and CAD file. On flat and built-up roofs, scuppers are utilized to provide an outlet via parapet walls or gravel stops to allow drainage of surplus water. In order to redirect the flow to the proper place, they can be used in conjunction with gutters and downspouts. For more details and Information download the drawing file.
