Jones Stephens’ 3” x 3” PVC Plastic Two Finger Closet Flange pushes easily into a 3” or 4” cast iron or Schedule 40 DWV pipe and has been designed to fit oblong horns. With a double lip ASTM C-564 rubber gasket and positive seal, there is no threat of leaking. This flange fits flush with the floor, and no tear out or caulking of the existing pipe is required for installation.
