Hard thick Black plastic spline from a Forever 1999-2000 storm door where you can insert a screen full panel or a glass panel pending which season

I'm not sure which size to actually ask for so I am taking a picture of it and sending it. I saw the you tube video and I understand that I can not use the nylon pet screen and I have to use a regular metal screen to rescreen this door. I just need 18ft. of the correct spline to rescreen. Thanks!

This looks a lot like our 55-109 screen spline. Check it out and see what you think.
