Marketing InformationMIFAB® R1940-SJ Series with cast body (specify material type) (nickel bronze or stainless steel) and slip joint inlet, wall anchor flange with countersunk holes and decorative outlet nozzle. The slip joint inlet downspout nozzle performs the same function as the R1940 downspout nozzle. The difference between the two is the method of connecting the pipe to the inlet. The R1940-SJ has the inlet machined out. This allows cast iron or PVC pipe to extend past the face of the finished wall and rest against the pipe stop. The pipe is secured to the inside of the R1940-SJ via three vandal-proof screws.
