This labor saving cleanout uses our Twis-to-Floor® adjustment technology to level the top with adjacent surfaces after the floor is poured and floor coverings are installed. Constructed of Duco coated cast iron and topped with a 6” (180) diam. nickel bronze, threaded, watertight cover, it is engineered to support pedestrian traffic in hospitals, schools, institutional and industrial buildings. Cleanout is accessed with a spanner wrench.
