Hello, Jeff. We may be able to help but I need some more information. First, please show me a clear picture of the metal clip at the end of the cord. I do not see it in your pictures. Please also tell me the weight of your sash. Please also confirm the length of the metal channel; I feel it should be 30". Thanks!

From your photos, it looks like you might have our S770-29 tilt balance. Please compare it to your own balance to confirm.
Now, regarding the stamp option. You say your sash weighs 25 pounds, which corresponds to our 29D option. However, the balance you have has old markings (2900) for a sash weight of 18 through 23 pounds. Before you order, recheck the sash weight. Did you ever find that your old balances were too weak? |
