I need to replace the coils counterbalance for about 4 sashes. The window sash weighs about 19 lbs on my floor scale. It looks like a dual coil system. The coil is about 1/2 inch wide, there is a DL6 printed on the lower coil and just a D6 on the other.

We don't have the exact balance system that you have, but I believe our S140-12 Quick Tilt Dual might work. To confirm, I need to see your pivot bar to see if it will fit in the S140-12 shoe.

It looks like a fit to me.

Aha, thank you. Unfortunately, your pivot bar won't fit in the S140-12 shoe. You would need to replace your tilt bar with either our 26-405 or 26-398. See if either line up with your current screw holes.
