Roof vent screen

Howdy all,
I am driving a 2005 Ford E350 extended top van that has a commercially available roof emergency exit/air vent. I am seeking a removable bug screen I can install on the inside of this vent and take it down or quickly move it when I need to open or close the vent (or use the emergency exit). Any leads?


I bought a couple of those large plastic type cardboard garage sales signs, cut a square out of the center of each of them to create a frame, then sandwiched screen between them. I attached it under the roof vent with velcro.

That. Is. Genius!!!
Thank you! I’m going to try this out right now.
