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.

A rail boot as set forth in claim 2, wherein said first and second elastomeric materials are thermally bonded together at said specific locations as a coextrudate during coextrusion of said body. 4. A rail boot as set forth in claim 3, wherein said elastomeric materials have different durometer hardnesses, and said second elastomeric material is tougher and harder than said first elastomeric material. 5. A rail boot as set forth in claim 4, wherein said rail head has an upper surface and said boot has a generally U-shape cross-section for partially encasing said rail remote of said rail upper surface, said body including exposed top surfaces, inside surfaces for engaging said rail and outside surfaces spaced from said inside surfaces by a plurality of longitudinally extending cavities, and a bottom portion for receiving said base of said rail, said protective layers being located along at least one of said top, inside and outside surfaces of said body. 6. A rail boot for isolating an embedded rail having a rail head including an upper surface and a base extending along a rail length, said rail boot comprising a coextruded body formed of at least first and second coextruded elastomeric materials, said first elastomeric material forming the bulk of said body and said second elastomeric material forming protective layers at specific locations on said body, said first and second elastomeric materials being simultaneously coextruded and thermally bonded together at said specific locations as a coextrudate during coextrusion of said body, said elastomeric materials having different durometer hardnesses, said second elastomeric material being tougher and harder than said first elastomeric material, said boot having a generally U-shape unitary cross-section for partially encasing said rail remote of said rail upper surface and a length extending along said rail length to isolate said rail from surrounding embedment material, said body including exposed top surfaces, inside surfaces for engaging said rail and outside surfaces for engaging surrounding embedment material, said outside surfaces being spaced from said inside surfaces by a plurality of cavities extending along said length of said body, said protective layers being located along said top, inside and outside surfaces of said body. 7. A rail boot as set forth in claim 6, wherein said body also includes a bottom portion for receiving said base of said rail, said inside and outside surfaces also extending along said bottom portion, and said protective layers are located along said top surfaces of said body, said outside and inside surfaces of said body adjacent said rail head and said outside surfaces adjacent said bottom portion of said body. 8. A rail boot as set forth in claim 6, wherein said body also includes a bottom portion for receiving said base of said rail, said inside and outside surfaces also extending along said bottom portion, said bottom portion of said body includes generally horizontally and vertically extending portions, said outside surface of said body extends along said horizontally and vertically extending portions, and said protective layers are located along said horizontally and vertically extending portions of said outside surface adjacent said bottom portion of said body.
