Searching for Polls door seal

Could you remove a sample of the seal and show us its end profile? That cross-section view would help a ton in narrowing down your options. In the time being, view our selection of weatherstripping here.

Thanks for sending these photos. This is a bit of an odd one. I'm afraid we don't have any kind of weatherseal that functions like this. where the seal portion itself (what I believe is the ribbed stem) is facing the same direction of the kerf (the arrow shaped stem in the middle). This is very uncommon, and nothing in our inventory quite works this way.

I'm not sure where you may be able to find this, especially if this is an older door. I think your next best bet would be a local shop with some history in the area, like a mom and pop kind of hardware store. They may have an idea what this could be if they're familiar with homes in your area.

I'm sorry that we can't be of more help.
