Hello! As long as the diameter of the outer tube is 3/8", and its length is 28", then I agree that our S900-28 is your best option. You'll also want to weigh your sash on a scale to determine the correct color option. The White Tip you have on yours may not be the same as modern White Tips. Back in the day, White indicated heavier sashes, but now it indicates light sashes. It's better to check and refer to the chart on our S900-28 store page to be sure. |
