Looking for (4) Milgard window channel balances. They are 12" in length. There are no identifying numbers. Attached are pictures. Please advise what model number I need. Thank you.

Hello,
With this combination of attachments, you could have either an 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. You'll also need to locate the stamp on your metal channel to choose the corresponding strength option.
If there is no stamp, you'll need to weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight.
Thank you and let us know if you have any other questions or concerns.
