Weights of the sashes are 23 lb. and 13 lb.

The Top on the large is 540 not 340.

Bottom 740

Am I looking at 5 and 7 lb. springs ?

For the smaller window weighing 13 pounds, see our S170-7 coil spring. For the larger window weighing 23 pounds, see both our S150-8 and S150-4 coil springs. Look them over and let me know if you have any other questions.
