Channel balance for amercian standards windows

Thanks for posting. Sounds like you have a 25" block & tackle balance with a stamp option of 2450. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.

I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
