ABSTRACT:
A closet flange is provided for coupling the base of a toilet to a drain pipe. A main generally cylindrical body portion is dimensioned for connection to the upper end of a drain pipe and has a through bore for communicating with the interior of the drain pipe. An attachment flange portion extends radially outward from an upper end of the cylindrical body portion and is configured for connecting to the base of a toilet. A knockout temporarily seals the through bore and is removable by breaking away a peripheral edge of the knockout. A retainer extends radially inward from an inner wall of the cylindrical portion below the knockout and is configured to prevent the knockout from falling down the through bore and into the drain pipe when broken away in order to prevent drain clogging.
