I am looking at using these coil springs to support a window on a custom application that I am designing. I need the window to move at least 24 inches. What is the working length of these coils, and if less than 24 inches what coil in the 12-13lb range would you recommend?

Hello! The maximum travel length of our S159-12 is 40". Would this be sufficient for your project?

Please note that these products are made to work as replacements for very specific existing hardware and are not intended for unique or custom applications. Even if the maximum travel works with your project, there is still no guarantee that these parts will work for you.
