I have the same issue. The builder said they don't supply screen doors for lanais. So what happens when small bugs get in the lanai?

T&D screens told me my sliding glass door didn't have a specific rail for a screen door. 1-352-748-0061 in Wildwood
You have to install a screen door rail which fits on the outside of the sliding glass door plastic frame and you fit the screen on that rail.
So you may or maybe not have a rail with your sliding glass door to put on a screen
Apparently T&D can look at your house number in order to figure this out.
You pick up the unit.

My door looks different than the one you posted. As soon as I figure out how to post a photo, I will do it.
