Title: Research carefully first
Review: I used this waxless seal on 2 toilet bowls, one bowl new, another from the 1940's?, and draininginto lead closet bends the tops of which were about 1-1/2" from the finished floor elevation. Theyworked great in both cases, although I could not use a standard floor flange, I had to use a floor flangeextension only( the flange without any tube), screwed down to the finished floor. I also needed to enlarge the center opening of the floor flange extension so that the seals on this product passed through it easily, and down into the lead closet bend. As I commented on J Martin's review, explicit diagrams or drawings made readily available by the manufacturer, of the exact dimensions of this product, would help someone planning to deploy it. 4 out of 5 stars because it worked for me.
Is this product review negative?
