it sure looks like it could be a seal. Could you remove a portion of it from the window and send us some photos from an end profile with measurements? |

Hello, We believe our 55-189 bronze snap in glazing might fit in your window sash. Please compare the dimensions on our product page to yours. Thank you! |
