I'm afraid the only thing I can tell from this picture is that you might have an Atrium door. However I cannot be sure exactly what roller it is you need, since they used many different kinds. The only way to be sure is to see a picture of your roller removed from the door. In the meantime, I've made a list of possibilities which you can view on the right side of this page.
