I have 3 different lengths. They are marked with numbers 2810, 2220 and 1610. Which series are they?

Hello,
With this combination of attachments, you could have either the S378, S380, or S385 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.
The spring strength options for the replacements correspond to the stamp codes on your original balances. Thank you, and let us know if you have any other questions or concerns.
