To check on the needed stamp option for this series balance remove the window sash and place it on a scale.
S751-25 with stamp option: 25R will carry a window sash weight range of 10 through 18 pounds 25HD will carry a window sash weight range of 18 through 22 pounds 25TG will carry a window sash weight range of 22 through 30 pounds This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate. |

Thank you for submitting your photos to us.
Have you confirmed your balance length to be 25", the metal portion only? If so, it appears you will need the S751-25 Channel Balance with the 24R stamp. |

Unfortunately you will need to replace the entire channel balance. The cord cannot be repaired.
