Simonton double hung tilt in windows

Hello,

Take a look at the video below that shows the parts that we recommend to replace your Simonton coil assembly, as well as demonstrates the replacement process. 

You'd divide the sash weight by the number of coils you intend to use on each side to support it to choose the correct strength options. I would recommend using two S159-6 springs for the 25-pound sash. For the 32-1/2 pound sash, I would use a S159-8 and S159-7 on each side. For the larger 33-1/2 pound sash, one S159-9 and S159-7 on each side would work. Don't worry about the two larger windows using two coils originally. The spring strength is more important than the number of coils used. Thank you!  

Correct, you would use two S159-6 coils on each side to support a 25-pound sash. A total of four coil springs. 

Sure, you would follow the same video that we included in our original response but you would install an extra S159-6 coil and 15-255 on top to attach to the opposite side of the pivot shoe. 

I'm sorry for the confusion. You are correct that you can attach the T end of the top coil to the small opening at the base of the first coil. 

We can't determine which latches your window uses based on the balance hardware but we would be happy to look into this for you as well. We would need to see photos of an undamaged tilt latch uninstalled, along with written-out dimensions, to compare to our inventory. 

Thanks for getting back to us. I would recommend removing your latch to compare to the specifications of the 26-243 and 26-244 shown below. If the dimensions match yours, then you should be good to go.
