Articulated pieces are used for producing connections to structures such as shafts or gullies. There is a distinction between articulated pieces for the inlet (GZ) and the outlet (GA) and for installation in a building (GE). Installation pieces (GE) are completely or partially unglazed, thus guaranteeing a tight integration into the shaft wall.
