I'm not sure about the screen. I'm sure it has a screen, at least thought it had a screen till you asked me?
I just ran out and checked and it has an aluminum frame on the passenger/door side of the trailer, it also has a little black plastic clip to keep it secured on the outter part of the frame of the window.
I'm glad it has a screen because we like having lots of windows
open all the time. thats what I dislike about the bolers. they have less windows that open vs. the trillium
. I wish the front window opened too but it doesnt. i've seen a few bolers that do. not sure where they got those windows of if it was an option or what? back window on this boler
here is kinda shady, the way it works. don't like the plexi in it, its just a bad design to me. with a bow/bend in the middle of the frame and the plexi has to bend around it to open. wish it had windows like the trilliums/side boler
windows. those are the best windows ever. they are so good in the rail and you get so much ventalation. its great.
