I have been trying to replace metal spline on Anderson screens but struggling. I think .250 is right (i have .230 just a bit too small). I don't want to end up with another pile of spline that wont work. Do you know if .250 or .270 is a better choice?

We find the 59-250 works well with Andersen screens.

What constitutes "old" versus "newer" screens. At approximately what year did they change?

Good question! I think it was around 1980. The width on the face of the screen was 1", but the newer ones are 3/4" wide.

My house was built in 1988 and has Andersen screens. According to above, my screens are considered "newer", so I should use the 59-270. Do you agree?

Yes: if your screens are newer then you should use our 59-270, as outlined above.

Paul's post from May 20, 2013 states he doesn't believe that the type of screening would affect the spline size choice. I am replacing my screens with Phizer Sun Tex 80 Solar Screen, which is considerably thicker than normal screen. Should I make an adjustment to the size spline I order?
