Inner Door flap didn't come with a screen insert, you have to put this on a screen you already own, then cut down the screen against the frame and place it inside the flap.
Swings both ways. Magnets slow the door down and stop it in place after 3-4 swings. Two plastic tabs removed that push into a hole to lock the door to stop pets in and out, double-sided slots lockable.
