Hi there! This looks like a typical tilt-window spiral balance. If the outer white tube is 3/8" in diameter then I would recommend our S900-28 as a replacement. |

It is very likely a white tip that has become discolored, but the old fashioned White Tip is not the same as modern White Tips. My recommendation is to just weigh your sash on a scale and refer to the chart we show on the S900-28 store page. |
