Each spacer includes spaced apart first and second faces, and spaced apart inner and outer edges extending between the first and second faces. The inner edge defines an opening extending through the body, the opening sized to permit passage therethrough of the through pipe of the closet flange insert but not the toilet connecting flange of the closet flange insert. With the subject invention, a system is provided which allows the closet flange insert to be mounted atop an installed closet flange flush with surrounding finished flooring.
