We have a Pella sliding door that uses Kerf Mount bubble seal. From process of elimination it has to be either the 58-153,-114, or -053. After taking many measurements & pics, we've determined the diameter of the bubble is 7/16ths, the length of base extension is 5/16ths. As you can see, none of these 3 choices matches exactly. At this point not sure whether to go w/a closer match on the bubble diameter, or the base extension. Hoping you can help. Thanks, Linda
