Hello, A few things come to mind since I see that you ordered the S600-16 white tip spiral balances. First, the white tip is only calibrated to support a window sash between 4 -10 lbs. If your window weighs more than 10 pounds, that would account for the problem that you're having. Another possibility is that the balance spring is not charged enough. Spiral balances need to be charged using something like our 75-006 tool or needlenose pliers as shown in our video below. Take a look and see if you may need stronger balances or if the ones that you have may need to be charged. |
