We offer a wide selection of standard and ornamental rainwater hopper heads. From very simple designs to elegant castings we have a something for both traditional and contemporary projects. Also known as conductor heads, leader heads, rain boxes, and scupper boxes, rainwater hoppers were traditionally designed to increase the flow of a drainpipe in heavy rainfall. With rainwater pipes usually running at just a third full; a hopper creates a symphonic system causing the pipe to fill to capacity and can also funnel drainage from two or more downspouts into one rainwater pipe.
