Thanks for posting. Before I can confirm what Series channel balance you have, I'll have to figure out what your bottom shoe is. Please look at the measurements for our 15-001 and 15-002 bottom shoes and note their depths. As you can see, they are 1-1/8" deep and 1" deep, respectively. Which measurement more closely resembles your own shoe?

Thank you! In that case, I recommend that you look at our S390-26. Does that look about right?

Glad to hear that our Series 390 looks good. Now, you say your window sash is 31 pounds. Order the S390-26 with the 2565 stamp option, which can support 30 through 33 pounds.
Please keep in mind that the above weight range 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. |
