Abrégé

A pull across screen assembly has a flexible screen member (e.g. flymesh) wound about a vertical rod positioned at one side of the opening. A line member arrangement is attached to the front of the screen member and part of the line member winds about a tapered drum which is positioned on top of rod and which rotates with rotation of the rod. The arrangement allows the screen member to be tensioned and also to be balanced as it is pulled across the opening.
