I purchased this as a replacement flapper for my Eljer toilet. Unfortunately, it only works with certain models...mine not being one of them. But if you think it will fit your toilet, beware....The chain attached to the flapper is only FOUR inches long! With no way to attach a longer one to it. How in the heck are you supposed to make that work?? Also the bulb that sticks out from the bottom is made of Styrofoam!!! Don't think that's going to last long! I ended up going to Home Depot and getting a universal flapper that hooked up quickly and works great!
