Hi, One of my windows balances broke on both sides, top and bottom. I need to replace. The brand is Simonton Prism. I've attached the images for the balance, the balance foot, the window foot, and the serial number. Thanks!

Hello! I have good news and bad news for you. The bad news is that Simonton no longer makes this balance type. The good news is that you can use the Certainteed brand coil balance parts instead. See our 15-192 pivot shoe, as well as our Series 170 bottom and Series 171 top coil springs. The video below will show you how these are all put together.

There is one important thing to note, which is that your old pivot bar will not work with the new 15-192 shoe. You will need to reuse the metal cam from the old pivot shoe, so make sure you don't throw them out!

Thanks for the information! Can the pivot bars be replaced with a compatible one? The metal cam broke on one of the shoes, as did one of the pivot bars.

That's an issue, then. The only pivot bar around that can replace the old Simonton model is our 26-336. However, this is not compatible with the 15-192 shoe. The problem is the "collar" that wraps around the front tip.

You can still get the 26-336 to work with the 15-192, but it will require you to grind down that collar until it's totally flat on the top and bottom. I know that's not ideal, but it should work. There is also no other option known to us. I apologize for the inconvenience.
