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 such as asphalt, vinyl tile or linoleum are installed. Its 6” (150) square nickel bronze top is recessed 1/8” (3) to receive an inlay of the floor material for an unobtrusive appearance. Constructed of Duco coated cast iron, this cleanout is designed to support foot and medium load wheeled traffic. It is available with 2", 3" and 4" outlets.
