Two of my windows need replacement channel balances. The windows are dual glazed, aluminum, single hung, about 30 years old.
Window 1: Channel is 1/2 inch wide x 34" long. Window is about 15 lbs. The channel has the following imprint: 3320A B.S.I. (A is upside down - see photo).
Window 2: Channel is 1/2 inch wide x 22" long. Window is about 15 lbs. Channel has the following imprint: 2130V B.S.I. (V is upside down - see photo).
The photos of the entire thing is the 34", but the shorter one is exactly the same.
Please send link of what I need to order or let me know should you need more information or photos. Thank you.

Hey Tom. It looks like the bottom fitting has side tabs, or what we call 'wings', whereas the top fitting does not. Is that correct? If so, see our S350-22 and S350-34. Review the diagrams below and let me know if this looks right. For the 22" balance, choose 2130 for the stamp option; for the 34" balance, go with 3320. Let me know if you have any questions or concerns.

There is no one tab version that I am aware of, so in all likelihood yours just snapped off. It happens all the time. I feel confident that this product will do the job for you. |
