CertainTeed casement winow

Thanks for reaching out to us. I'm afraid we don't sell an exact match for this seal. The 58-056E was the first to come to mind but this is meant for doors. We also have the 58-170B, though this still differs. Take a look at the specifications for each and see if you think you can adapt one of them to your casement window.
