Looking to replace three window balances in MI windows they measure 34 1/2" high and 33" wide the springs are broken on the balances and they have a number 740 stamped on them . Replacing the springs would repair the balances in these older windows. Would need six of the 740 coil springs if you have them.
Thank You
Ken

Thanks for writing in! There is a good chance that we can supply you with the replacement balances you need. I'll just need see a photo of the balance assembly removed from the window. Unfortunately, I cannot identify them based on the stamp from the coil alone. Please let me know if you have any questions in the meantime. |

Thanks for writing in! Your coil balance pivot shoe looks a lot like our 15-180, although it is slightly different in design. These are compatible with the Series 190 Coil Balance Spring. Specifically, you'll need the S190-740. I've linked a few of the other compatible parts as well. |
