Abstract

A retractable flexible screen for installation to a frame of a fenestration product, the frame having opposite pairs of frame members. The flexible screen extending and retracting across an opening in the fenestration product and including flexible screen material and a roller system upon which the screen material is unwound and wound. The roller system mounting to a pair of mounting brackets, each attachable to one of the pairs of frame members. A control bar connects to the screen material and moves along a pair of tracks each mountable to the same pair of frame members, the screen material extending from the roller system to one of the other pair of frame members. A gripper system mounts in the tracks and grips the screen material in a closed flexible screen. A spring tensioning system provides post-installation access to adjust the tension of a spring within the roller system.
