86A 27-4 BA2 CMC 7 Replacement Balance Needed

A quick learner from Broomfield, Colorado says:
Had one spring cord break and need to replace balance. Non-tilt sash. 28" measured channel. Stamp says 86A 27-4 BA2 CMC 7. Will S385-28 (2740) work or do I need something different?

Hello,

We can supply your replacement balances but your stamp code indicates that it will need to be a custom order. We just sent over an order link and price quote for you to review. Take a look and let us know if you need anything else. Thank you!
