Please see the attached photos. I have a total of 8 windows, most of which still work fine, however I am in need of 7 of the balances. These windows are all 58" high. From what I have seen on your website the balances would all be the same. Is that correct and if so, I would like to order 7.

Hello! I recommend our 24-1033. This can replace Andersen balances stamped with "10#27." You may want to double check the other balances, just in case. If the windows are identical in every way, there's a good chance the balances will be the same, but if there's one thing I've learned in this industry it's that you can never be too sure.
