ABSTRACT:
A method and apparatus for rapidly and reliably sealing off a selected opening from an adjacent path of smoke, noxious fumes or contaminated air which comprises a reel of reinforced transparent, temperature, chemical or radiation resistant material having flexible magnetic edge strips on each side thereof mounted and centered above said opening, and causing the reel to drop in vertical fall adjacent to the opening and simultaneously causing the flexible magnetized strips to become rapidly and magnetically attached to ferromagnetic side rails or ferromagnetic door frame used for fire doors and to expand under pressure while maintaining an air tight seal of the opening. This apparatus is elegantly simple and reliable in both its construction and operation and has an extremely high price/performance figure of merit.
