ID bead molding

I'm afraid I can't ID your weatherstripping based on this photo. Its condition is just too deteriorated. Is it possible to see an undamaged sample? We will still need to see it from the end profile. The video below will clarify what I mean.

Thank you. Unfortunately, we don't have a weatherstripping type that matches this. The issue is the kerf; yours appears to just be a little nub, which isn't something we have.

My recommendation to you would be to contact a local hardware store and bring them this sample. They may have something you could use or, if they're familiar with homes in your area, they could point you in the right direction.
