Closet Flanges

Sioux Chiefs closet flanges do what flanges are designed to do anchor the toilet to the floor and make a secure connection to the drain. And they do so with the quality and attention to detail contractors have come to expect from an American manufacturer. To Sioux Chief, closet flanges represent an opportunity to make another group of rough plumbing products better. Better for distributors, better for installing contractors.
