My window is non-tilt sliding, the 1/2 inch balance measures 28 inches metal end to metal end. It has a 1 1/4 inch non-winged tip (top) and a 1 inch winged bottom end. The balance has stamped on it: 27 4 KQ CALDWELL
Do you have a compatible replacement ?

Hello,

I see that you were looking at the S350-28 channel balance, which I agree looks like a match to your assembly. You would also need a 2740 strength option based on your 27 4 stamp code. Please note that the bottom fitting measures 1-3/32" as shown below. Thank you!
