A new perimeter warning line system by Jescraft provides rooftop workers with a visual warning that they are dangerously close to the edge of a roof. Designed for fast and easy setup, the portable system conforms fully to OSHA regulations and requirements when properly assembled. In addition to rooftops, the 100-foot perimeter warning line system can be used at other types of jobsites to identify hazardous areas. The warning line system is made of powder-coated steel and includes cross-stand style bases that fold for easy carrying and storage. For more information, visit www.jescraft.com.
