Jim after looking at your pictures it appears that you have a design where
the screen frame is set into a piece of channel that holds the rollers.
Look at the end view of the door to confirm this, If this is the case see if
you can separate the channel from the screen frame, and coax the channel
into position and then set the screen frame into the channel.
On all the patio doors I have worked on, the screen has spring loaded
rollers on the bottom and spring loaded glides on the top. To install, you
slip the top into the track and push all the way up, then push up the
rollers on the bottom to pop them over the track.
Hope this helps.
