Hi there! Thanks for reaching out to us. We'd be happy to help with this. Before we recommend anything, can you show us a photo of the original pivot shoe? Seeing it removed from the window sash would be ideal but let us know! |

This is perfect! I appreciate you getting that for us. The 15-192 and Series 170 can replace your old shoe but it will take some modification. For example, the aligners or "bumps" on the face of our pivot shoe will need to be ground down. Reusing your old shoe's metal cam may also be necessary. However, please note that modified items cannot be returned. Furthermore, you would need the 15-156 cover and 15-157 balance drum for the new springs. The other option we have is the 15-259 which uses the Series 159 coil springs. The video below will go into the details, including the additional parts needed. Just note that you will need the exact weight of your sash on hand to calculate the proper spring strength. You want to divide that weight by how many springs support the sash, then pick accordingly. |
