Marvin aluminium clad fixed windows vinyl glazing bead.

Hi George. Can you remove a sample of the glazing bead and show us its end profile? From there we'll do our best to find a replacement. In the time being you can view our selection of glazing bead here.

I'm afraid I still cannot determine what you have from this photo. We need you to turn it so that the end of it faces the camera. I recommend looking at our complete selection of glazing here to get an idea of what kind of angle we need. 

I'm afraid that we don't sell a glazing bead that matches these specifications. Marvin has exclusive rights to many of their products, so this may ultimately not be something we can help with. I think you would be better served contacting them directly for assistance.
