A quick learner from USA says:
I have Andersen 400 series casement windows. What screen material, spline and tools do I need to replace them? Thank you, Pete

Thank you for your patience during this busy season. For the tools you will need, I recommend using our 75-019 along with a 75-082 razor knife and a scratch awl like the 75-029 to remove the existing screen spline from the frame. 

For the size of the spline, I'm not sure what size the newer 400 series Andersen windows take. I know the older screen took the 59-250 or the 59-270 . The newer screens might take a thinner spline like the 59-150 . That's just an educated guess though. You will need to remove a section of your screen spline and match it up to the ones we have on our site.
