Window seals for Atrium Bay Window

Thanks for writing in. There's a few possibilities. Can you remove a sample and show us the end profile dimensions? That would help a ton in narrowing down our options. The video below explains what we'll need to help you. 

Thanks for getting back to me, Greg. This looks like an older type of glazing that is quite a bit thicker than anything we carry--our glazing bead is all thinner vinyl. The closest shape we have to this is our 55-029--again, it's much thinner, and I can't make any promises, but it might work as a substitute. See the dimensions below to confirm. Another possibility is a thicker window gasket, like our 59-067. It's not the same shape, and I think it might be too small, but take a look at the image below for comparison. These are our closest matches. If you try either, let me know how you make out.
