I need to replace 4 balances here is the picture

Hi there!

To identify what type of channel balance you have, we'll need you to remove an undamaged balance with the end attachments intact to compare to our inventory. The video below will explain this more in detail. 

Thanks for the additional pictures!

With this combination of attachments, you could have either an S380-28 or S385-28 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need a spring strength of 2740.

If you have any other questions please let us know.
