Spring Balances

Thanks for you entry. I see that your window could be using our 15-180 pivot shoe along with the Series 190 coil spring, 15-181 double support clip, and 15-182 balance bushings. With your sash weighing 20 pounds, I believe you may go with our S190-540 coil springs on each side. You may want to reconfirm if the old springs have the same code number.
