Abstract: A security screen device for protecting persons and property is provided. The security screen device comprises an enclosed screen housing defining a screen receiving area. A screen material made of high strength fibers is receivable within the screen housing in an undeployed condition with the screen material having a first edge and a second edge. The first edge is secured within the screen receiving area and a weighted bar is secured to the second edge of the screen material. An activation mechanism opens one side of the screen housing releasing the screen material from the housing into a deployed condition such that the second edge of the screen material travels in a direction generally away from the enclosed screen housing thereby pulling the screen material from the enclosed screen housing.
