Economical and durable bright red polyethylene roll flags are ideal for tailgates or overhanging loads. Perforated roll flags can be custom imprinted. Just nail or tie to the overhanging load or whatever you want a highly visible warning of a potential hazard. Perforated roll flags come standard in 3.0 mil polyethylene with an available 8.0 mil polyethylene for custom applications. Perforated roll flags are mainly for warning of hazardous exposure to asbestos or benzine.
