Have very large windows and my balances are 24E. They are of the 770 Balance style but see that you only carry 24D. Is there another option available? Seeing as these balances have worn out I'm afraid to put in 24Ds

We can custom make this balance for you. Please just confirm the weight of your sash, to be sure that the 24E is the appropriate option. Two S770-24 channel balances with a stamp of 24E can carry a window sash weight range of 25 through 28 pounds. If your sash weight falls within that range, then check out this Custom Channel Balance Request Form I've started for you based on your specifications and fill out the rest of the information. One of our representatives will get back to you with a price quote and an item to add to your cart.
