We have a single hole aligner, our 26-139, that fits into the track for windows that use a Series 600 spiral balance. These aligners help keep out the draft. We don't have anything for coil spring balance systems, however. I'm not sure if the 26-139 will work since it has that big hole in it, where a spiral balance ought to go. Perhaps if you found a way to plug that up. That said, if you're instead referencing the sash stop, look at our 26-338. This looks like a match for what I see in your photo. |
