25 inch long Channel balance that clips into pivot shoe

Hello! Your balance appears to match our S770-25. I am confident that this will repair your window, but look it over and tell me if you agree.

You're welcome! I think it looks pretty close, too. Thanks for reaching out to us and please let me know if you had any follow-up questions.

Oh, I see. If you don't have stamps on your old balances, then you will need to weigh your sash on a scale to determine it's weight. Then, refer to the chart we show on the S770-25 store page.

This is a very important step and I wouldn't guess or estimate the weight. Get an exact rating. The primary function of a this part is to counter-balance the weight of the sash, so you want it to be accurate.
