simonton windows Quick tilt coil spring window balance

Thanks for writing in! There is a good chance we can supply you with the replacement coil balance springs needed for your existing balance assembly. Although, I'll need to see a photo of it removed from the window to determine the best possible replacement.

The most important part I'll need to see is the pivot shoe and I'll need to know the stamp/markings from the coil balance spring. 

If you are looking to replace any of the other compatible hardware, like the pivot bar, I'll need to see a photo of this part removed from the window as well.

Please let me know if you have any other questions in the meantime.

Thanks for the photos.  Your Simonton Coil Balances have been discontinued and are no longer made. The good news is, we do have two replacement solutions that could potentially work for you. We typically recommend our 15-192 Certainteed pivot shoe to replace your Simonton brand part but you may need to shave down the aligners from the shoe to install it into the window. Take a look at the dimensions to confirm if it may work for you.

These are compatible with the Series 170 coil balances as well as the Series 171. The S171 is stacked on top of the S170 in situations where there is more than one coil. To confirm which coil strength you need, you'll need to look for any stamps/markings on the metal coil. If there are no stamps/markings, you'll need to get the window weight and divide it by the total number of coils in the window.

Please also be aware that we are also now recommending the 15-259 pivot shoe, which should fit well in the track, along with the S159 coils springs and either the 15-255 single support or the 15-256 double support. To use this assembly, the original pivot bars would need to be replaced with our 26-083. We are still in the early stages of confirming if this replacement is a good long-term solution but we have high hopes that it will work with little need for modifications, if any. Take a look and if you decide to give it a try, we'd be eager to hear how it works out for you.
