the old balance has this on the back: 26-3 AJ5 CMC 50
What is my "sash range"? Which model should I order?
Thanks

Hello, Unfortunately, the stamp on your balance will only tell you the spring strength required for your balances but will not help you choose the correct replacement. We'll need to see a photo of an undamaged balance removed from the window to point you in the right direction. Thank you! |
