Hello, I agree that the S395-27 appears to be a match to yours but the 26-3 stamp on your balance correlates to a 2630 strength option for a window sash weight between 13 and 19 lbs. I'd recommend double-checking the sash weight and if it is definitely 12 pounds, the 2620 option for a sash between 9 and 13 lbs may be the way to go. Thank you! |
