Good Morning,
If you have a tilt window, you will need the S600-23 replacement balance with the 'blue' tip option and the 75-006 charging tool. If you have a non-tilt window, you will need the S500-23 replacement balance with the 'blue' tip option and the 75-005 charging tool. Make sure when you measure you old spiral balances, that you are just measuring the metal portion (do not include the blue tip in your calculation). |
