I am looking for replacement window latches. Many of my double-hung windows have broken latches. The numbers on the back are .075 - Pat. Pend. 5,139,291 - 7R (or 5L). The installer has not been able to help me locate this part.

Thanks for contacting us. Please see our 26-391 and 26-390 tilt latches. These are similar in design to what you have here, but you should go over our dimensions to confirm that everything matches up. Let me know!
