Hi there! Thanks for reaching out to us. Given that this is a Peachtree brand window, our Series 745 may be what you want but I would need to see an undamaged balance removed from the window to confirm. You will also need to weigh the window sash on a scale to determine the proper spring strength option. |

For a 20-pound sash, you would use the S745-32 with the 31.25-3 option for a sash weighing between 17-23 pounds. |
