Double hung window spring counter weights

Hello,

Your channel balance resembles the S765-27. Your stamp code indicates that you'll need 26-5 strength options to support a sash between 17-23 lbs.

As for your broken frame, unfortunately, that is not something that we can supply and would be specific to the manufacturer. If you need the pivot bars, we would need to see yours fully removed with written-out dimensions to confirm the best match. Thank you.
