I tried to get the seal out of the frame but was unable to do so. It is stuck(22yrs). I don't think the 58-189 part will work in my situation because the center to center distance on the frame is slightly less than 3/4inch on my frame. Maybe a whole new slide on piece with the rubber seal on the bottom instead? Hope this makes sense.
attached is the bottom piece of my screen doors. I measured the rubber piece the best I could and it looks like the measurements are 3/16 X 7/16. I noticed you have a similar piece online(40-172) that may fit (1/4 x 9/16). My measurements may not be exact so am wondering if the 40-172 is the best option or maybe you have something else that would fit better.
Thank you
