Thanks for reaching out to us. I'm afraid the Series 770 won't work for your window. In your case, the jamb liner itself is the balance. In my experience it's not possible to put another balance inside that liner. Is this a wood window? If so, you can contact a local mill work to set you up with new jamb liners. If not, you will need to contact the original manufacturer of the window for assistance. We can at least replace the shoe itself, which would be our 20-022. |
