Advice of Purchase

Dear Sirs,

I am trying to match up your products with what I need to replace on several windows at my home. The current items is aluminum. Best measurement I can get is 9/16" on the curved side. I could go down to a 1/2". There is no lip on the flat side. On the window lip it is 2/8" (1/4"). Please make your best recommendation so I can purchase the appropriate product. These glazings are from 30 year old Lawson windows manufacture in the Miami area. The wide side which measures 9/16" is slightly curved.

Thanks for any help.

Regards,
Mike D
