Patent abstract

A closet flange includes a body having a lower body portion containing a bore and an upper body portion containing an inlet opening in fluid communication with the bore. Within the body is a knockout for closing off the bore. The knockout has a frangible connection with an interior wall of the body and one or more portions that extend radially outwardly into a portion of the inlet opening that has a larger diameter than the bore to permit the knockout to be broken out of the body while preventing the knockout from passing all the way through the bore.
