Simonton window coil balance replacement

Question

Hi,

One of the coil balances from a Simonton window has broken. From the one picture, you may be able to tell how the plastic piece has been broken in two (I lost the other half of the piece).

I can't determine from your list of parts which replacement piece I would need. I'm also not sure if you can tell that from these pictures, either. If you require, I can remove the other good coil balance and send pictures of that one instead.

I also don't see any identifying names or numbers on any of the pieces above.

Thanks in advance for any help you can provide.

Regards,

Ken

Thanks for posting. Simonton 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. You may also need to reuse the center metal cam, since the new one may not fit with your existing pivot bar.

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.
