Could we see some photos of the coils you are looking to replace? As for the weight, since there are no stampings on the coil, we would need to know the weight of the window sashes.

Thanks for the photos. Now we need to know the weight of the window sashes so that we can get back to you with some appropriate product codes to review.

Thank you for the additional information. We have similar parts you should be able to use. The pivot shoe will be the 15-111. We believe you have 1/2" wide coil springs, so you should be able to go with our 15-150D nylon spring housing for holding two coil springs. For single spring go with the 15-150S with the 15-148 rubber bumper. For the 26.8 lbs. sash use one S160-6 and S160-7 on each side of the sash. For the 22.2 lbs. sash use two S160-5 on each side of the sash. For the 9.4 sash use one S160-5 on each side. Please confirm by checking the numbers on the old springs. With the way you show the coil spring set up is incorrect. The top coil spring should actually hook to the bottom spring hole and the bottom spring hooks to the pivot shoe.
