Balance

I have a wild guess. You should check it. If I'm right, I'm right. If I'm wrong, I'll try something else. If you have

1. a tilt window
2. a 5/8" diameter spiral tube
3. and a 29" long spiral tube

then you can use an S600-29. The tip color can be matched to the color on your old balance, which is not visible. If there is no colored tip, weigh the window sash and compare to the chart on the webpage. A white tip sometimes means you need the lowest weight setting, which is a red tip in our system. Either way, weighing is the most certain method.
