Sash Balance 22" Series 770

Question

I have a Sash window that weighs 29.4 lbs. 22" inch Balance Stamped Unique 21-F-60 Manufactured date 04/07/1997. Your stamp weight option goes up to 27 lbs. As you can see from the picture The Series 770 should work with mine except the additional 2.4 lbs. I will need 6 balances to repair 3 of the same windows. What needs to be done for the additional 2.4 lbs of weight to the Balance?

Thanks for posting. We can furbish 22" Series 770 balances stamped 22F, which means they will be able to support a window sash in the weight range of 27 through 30 pounds. This is not a stock item for us but we can provide it via custom order. I just sent you an email with a custom link to order 6. Let me know if you have any other questions.
