We can replace this balance, but it will have to be specially made. I will email you two special order links for each quantity and size requested. The balances we'll be using are a little different from yours. Specifically, they use a different spring rating system. For the 30" long balance, we'll use the 30C stamp for sashes weighing 19 through 24 pounds. For the 22" long balance, we'll use the 22B stamp for sashes weighing 10 through 16 pounds. You should weigh your sashes just to confirm that this information is correct. |
