Weather strip at the bottom of the window sash

Thanks for contacting us. I've seen this weatherseal a few times in the past. I'm afraid we've never been able to source it, so we won't be able to provide an exact match. That said, our 58-135 is similar in terms of how it installs. We've never had anyone confirm but it may be the closest match we have. Carefully look over its dimensions and let me know what you think.
