30 inches long, 1/2 inch wide. I do not know the brand, however there is a part number on the channel rod that says 2940 RK as shown in one of the pictures

Hello,

With this combination of attachments, you could have either an S380-30 or S385-30 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 2940 spring strength options for your replacement balances.

Thank you and let us know if you have any other questions or concerns.

The bottom attachment measures 1 inch so that would be a series 380, but how do I know the spring strength I would need?

Great, as we mentioned, you would need a 2940 strength option based on the stamp shown in your last photo.
