Hi, I need to replace the screen mesh and spine on my screen windows. How do I determine the size of spine to purchase?

Thanks for posting! The best way to identify what spline you need, of course, is to measure your current spline and match it up to one of the options we have online. If you don't have any spline available though, what is the measurement of the channel it fits in? I may be able to help you determine what you need based on that information.
