https://youtu.be/0pOuqsyaobc Found this YouTube video on how to make it easier to open screen door without moving the sliding part of the door. Took a few attempts to get the bends correct - but works great on my 27U.
I tried that - just did not work well for me and was always getting bumped when slide the little door open to lock up at night and had to reposition it frequently. This wire thing seems to work very well.
