Spline for screen door panel

Thanks for your patience during this busy season. I'm afraid I don't know if our 59-236 is what you need. I have nothing to compare it to.

This is a photo identification service, so the best place to start is to remove the original spline and show us a clear photo of the end profile, just like we show the 59-236. We also need all relevant dimensions written out in your response as precisely as you can manage.
