Hello, this is from an Alenco single hung vinyl that was installed around 1996. Is the correct replacement 15-179?

The 15-179 looks close, but that's all I can say. In order to confirm if it will work, you'll have to compare the dimensions we show on the 15-179 store page to your own. If they match up, then you should be good to go.
