Hello! The number stamped on your balance doesn't help us ID your hardware, unfortunately. We would need to see an undamaged balance removed from the window along with the intact attachments. |

Perfect, thank you! I recommend our 15-111 pivot shoe that is used with the 1/2" thick Series 160 coil springs. With a 20-pound sash, you can use (1) S160-4 4.5-pound spring and (1) S160-5 5.5-pound spring on each side of the window. This weight setup would support a sash weighing 20 pounds. If you need a new double coil support, see the 15-150D. |
