Color Tip Selection Chart
| Color Tip | Sash Weight Range |
|---|---|
| Red Tip | 06 – 19 lbs |
| Blue Tip | 10 – 29 lbs |

Weight ranges are based on using two balances per sash. Actual sash weight support may vary depending on friction from jamb liners or weatherstripping.
Best Practice
- For best performance, window balances should be replaced in pairs (sold individually). Installing one new balance alongside an old one can lead to uneven operation and premature wear. Replacing both ensures smooth, long-lasting performance.
- Whenever possible, select the same color tip as the balance being replaced. If the color tip you need is not listed or you are unsure which option to choose, contact our experts for assistance.
