25 5 CQ Caldwell

Thanks for your post! Your balance is similar to a few we supply. To narrow down the correct replacement match, I'll need to see a clear photo of the spring and the string on the inside of the balance. I'm particularly looking to see the piece connecting the two of them.

Please let me know if you have any questions.

Thanks for the requested photos. Your window balances can be replaced with the S378-26, S380-26, or the S385-26. To determine which of these is the correct series, you'll need to confirm the depth of your bottom shoe.

Our 2550 stamp will support a sash weighing 25 to 28lbs.
