Thank you for posting, and for the thorough information! Based on your dimensions, please take a look at our S600-20 spiral balance and see if that matches your hardware. For 26 lb. sashes, I recommend you use the blue tip. An S600-20 with a blue tip can carry a sash weight range of 10 through 29 pounds.
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. |

Please take a look at our instructional tutorial video on how to replace your tilt-window spiral balances.
