The Tractel PermaLine is a permanent, Non-Penetrating OSHA-compliant warning line system that remains intact until you want to move it. The powder-coated or galvanized metal flags are adhered to your choice of a vinyl-coated cable or galvanized aircraft cable which allows the flags to pivot and reduce wind resistance. This cost-effective design won’t tear or wear out, eliminating the need for replacement, and since no drilling is required, the integrity of your roof remains undamaged.
