Help identifying window block and tackle balances

Question

Can't find any markings or identifiers to help identify my brand of window. Have several windows that are in disrepair which seems to be from the same issue of worn out black and taco balances. I had already uninstalled the valances before I took the pictures. Just need help identifying parts so that I can place an order.

Hello,

With this combination of attachments, you could have either the S380-29 or S385-29 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 2830 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.
