A closet flange is the critical connection between your toilet and the drainage system below your floor. The Sioux Chief 888-PTM is a 3-inch Schedule 40 PVC closet flange designed for DWV (drain, waste, and vent) applications in residential and commercial plumbing systems. This flange connects your toilet to the waste line beneath your floor, providing the foundation for a functional drainage system.
The knockout feature sets this flange apart during installation. The inside knockout design allows you to remove the floor ring without holding it while hammering, which simplifies the installation process. This design also enables a flush-to-floor installation that works with various flooring types and thicknesses, ensuring a clean finish.
