ABSTRACT:
A device for allowing screen to be unrolled from a roll and applied to an open frame while simultaneously maintaining constant tension across the width of the screen. A roll friction bar is provided which extends closely parallel to the circumferential surface of the roll of screen. The roll friction bar is attached to the roll by insertion into the axial openings typically found in rolls of screen material. The free end of the roll of screen is brought around the roll friction bar, doubled back over the screen still on the roll, and fixedly attached to the open frame. The installer then unwinds a desired amount of screen from the roll. By grasping the roll with one hand, the installer is able to both prevent screen from further unwinding from the roll and maintain constant tension across the width of screen being applied.
