Hello, thank you for posting, Your balance assembly resembles the 15-177 pivot shoe that is compatible with the Series 152 coil springs. The coil springs should be marked with a number that indicates the weighted coil needed. If there is no number, please provide the weight of the sash to move forward! Alternate image for 15-177
Also review the 15-145 support barrel, 15-143 bushing and 15-144 bushing cap. Please also review the dimensions of the 26-466 pivot bar to see how it compares to your original. Let us know if you have any questions! |
