basement window snap in glazing strip

Thank you for your patience during this busy season. Unfortunately, I wasn't able to find an exact match for your glazing bead. The closest thing we have is our 55-306. This has that same ribbed kerf as yours, but this is specifically designed to be used on Andersen brand windows.  I don't know how well it will work on anything that isn't Andersen, if it will work at all. Just something to consider.
