T spline for Larson all screen doors?

I see a post above asking what kind of T spline is needed for a Larson screen door. You asked him to send a photo, but I can't see whether that was done. I want to buy a Larson door but I want to put my own screen in it so it matches the rest of the screen on the lanai. Have you determined what spline they use?
