Hello! I recommend our 15-177 which uses the Series 152 coil springs. Your old pivot shoe was discontinued but this can replace it. Take a look and let us know if you have any questions. Alternate image for 15-177

The Series 152 coil spring balances are sold separately. I recommend checking the band of the coil spring for a stamped number that indicates the weight. If there aren't any stamps or they're too faded, you will have to weigh the window sash on a scale and divide the weight by the number of springs in the window to determine the proper spring weights. |
