Coil window balancer

Thanks for your patience during these busy holidays, Kirk. I believe we can help with this balance, yes. It's close in design to a couple different Series. Before I can narrow it down, would you be able to show me a photo of the pivot shoe to which it attaches? That will allow me to pick out the best match for the job from among the possibilities.

Looks like you have the old Simonton brand coil balance assembly. They no longer make this, but we have two possible solutions for you to consider.

The first is our 15-192 pivot shoe, along with our Series 170 coil spring (and other parts related to its store page). This is a Certainteed brand part but I have had customers in the past tell me that they got it to work after grinding down the front of the face, which sticks out just a little too far for this window.

The other option is a more modern replacement that I think works just as well, if not better, since it's not prone to breaking in half like your old one is. The video below will go into more detail. This will explain exactly what parts you need to buy and how you can install them in your window. Just note that you will need the exact weight of your sash on hand in order to calculate the proper spring strength. You want to divide that weight by how many springs support the sash, then pick accordingly.

As for the operator, it would be either the 39-253LB or 39-438B, depending on the design of the guide at the end of the arm, which I can't see. We have another video that should help you decide on the best match.
