window balance ID

Question

I need some help identifying my window balance. It appears to match the S395 series, can you confirm? Also, the stamp shows 36 4 bx cmc 11. Would this indicate a 3640 sash weight?

Thanks for posting. You're 100% correct. This is an S395-37, and for the stamp option you'll choose 3640. Let us know if you have any other questions, and Merry Christmas.
