ABSTRACT:
A preferred fenestration assembly includes a roll screen and a guide body presenting channels for receiving the respective side edges of the screen. During movement of the screen toward the closed position, the side edges are gripped between a shiftable gripper and gripping surfaces of the guide body. The gripping components are configured to release the side edges if excessive force is applied to the screen to prevent damage while retaining the side edges with a minimum level of force to withstand wind loading.
