Here are the pictures you requested to assist in the replacement . The strips are 1/2 inch and fasten under the outer edge of the window. The windows were manufactured by General Aluminum, series 1100-1450-1550-1900-H-R30. Does your company carry these replacement strips. Thank you very much for your assistance.

Thanks for reaching out to us. It's a bit hard to say from these photos. The 55-120-6 comes to mind though. Take a look and see how the specifications compare with yours.
