broken window shoe

Thanks for posting! You have a coil balance assembly that appears to be an older discontinued shoe that is no longer available. For this, 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.

There 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. The 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.

We are now recommending the 15-259 pivot shoe, which should fit well in the track, along with the S159 coils springs and 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.
