This is a Series 600 balance, considered the most popular spiral tilt balance in the industry and used in aluminum and vinyl tilt-in windows. It moderates the operation of your window sash to allow the window to stay open when raised.
- This balance has a 24" long metal tube. When determining the length only measure the metal tube.
- The strength you need should be indicated as a color tip at the end of your old metal tube. If you do not see a color tip weigh your sash on a scale and refer to the chart below.
- The metal tube measures 9/16" in diameter, but it is considered 5/8" in the trade, and houses an internal spiral rod with double pins.
- Can work for either the left or right side of the window interchangeably.
- Spiral window balances come fully lubricated and ready to be charged.
| Color Tip | Sash Weight Range |

*This information is based on 2 balances per sash. Balances are designed
assuming friction in the jamb weather-strip will carry a portion of the sash
weight. Suggested sash weights are approximate.
