channel balance replacement options

A home owner from Bloomington, Mn says:
I need to replace several channel balances. I have tilt out window. Your 25" series 751 channel balances appear to be what I would need. My current channel balances are simply stamped 24. They is no other lettering. Would this be a special order?

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.

I'm attaching a few photos for possible channel balance replacement. I need to know if your parts will work in my windows. It looks like your series 751 are identical to mine.

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.

Thanks for your response to my question. My only other question is whether or not my existing channel balances can be repaired. The cord in all of the failed windows has broken. Can the cord be replaced and then new shoes attached?

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