1/4" thick

Hello!

Thank you for reaching out to us. We don't have a good match for this glazing bead, unfortunately. Our 55-190 is the closest I could find but it is still very different so I'm not optimistic this will work. Your best option may be to contact the original manufacturer of the window if you can track them down. I am very sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions.
