To replace your original balance, order the S745-32 and choose stamp "31.25-4". However, this will replace a "3072" stamp for 24 to 28 pound sashes. If your sash is 20 pounds, you will want a lower option. Did you find that it was hard to close the window before, when your "3072" balance was still functioning? I'm wondering if your balance was too strong originally.

I thought that might be the case. For a 20 pound sash, I recommend the S745-32 with 31.25-3 option. That's for sashes weighing 17 through 23 pounds.
