I am in need of 4 channel balances all exactly the same as post photos. The length of the balance is 27 inches measured per your instructions. I think the part needed is S385 and not S380 . I looking for confirmation of which size width needed. Thank you ahead of time for your help and website!

Hi, Susan!

With this combination of attachments, you could have either an S380-27 or S385-27 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 option of 2640.

If you have any further questions just let us know.
