Hello,
Your channel balance resembles the S770-28. The stamp code does not correspond to ours but you may be able to use the 28E strength options for your replacements. I would recommend weighing your sash to confirm that it falls within the 28-32 lbs range supported by the 28E balances. Take a look and let us know if you need anything else. Thank you!

Hi Casey! Thanks for that info - I weighed the sash and it was between 32 and 33 lbs. Any further recommendations?

I found the weight list and went ahead and ordered two of the 28F! Thanks for your help!

Both 27E and 27F strength options will support a 32-pound sash, so you should be good to go. Just let us know if you need anything else.
