Fits my Kohler K-838-0 Bellwether 60" x 30" cast iron tub, great quality, costs more than planned but once you get over the difficulties make it a its weight in gold, it's a lot better than the plastic part which seems cheap and the finish is really wonderful, very durable. The lead pan has a slight angle, making it difficult to install other drains. You really feel the quality of the retro American.
