Hello! I'm afraid I can't help with any warranty your window has, but we definitely sell these balances. Since your pivot carrier is a match for our 15-087 I would recommend the Series 180 coil spring. You will need the stamp off the original in order to select the proper weight option. |

The stamp is usually printed on the band, usually next to the holes. If yours reads 7R then that likely indicates a rating of 7 pounds. |
