The SWF4846B is one of four available sizes, each consisting of four detachable steel flag-hinged sections consisting of a super lightweight, black powder coated aluminum frame. The white dual layer scrim faces are fire retardant treated and can be used in conjunction with lighting effects to create that perfect look for any momentous occasion. After the gig, if you find a stain on the scrim from an accidental drink spill or other mishap, no problem. All that is required is a screw driver to simply remove the scrim for cleaning.
