T-slot rubber window weatherstriping

Thanks so much for reaching out to us. We unfortunately don't sell this exact seal, though we did at one time. The manufacturer discontinued it some years ago.

At this time we have no verified alternative. The best option we can offer is the 58-135. This is a different design but works under similar principles. Look it over and see if you think it's worth considering as an alternative. I've never used it as a replacement for your original so I unfortunately can't say for sure, but it is my best guess.
