The Safe-T-Zone Permanent Warning Line System provides a cost-effective, durable, and permanent warning line system when other passive fall protection is not required. The aluminum warning pendants contain the word “DANGER”. This warning line system provides a permanent but simple solution for unprotected edges for irregular work in a facility or rooftop. This product works best on low-sloped roofs 15 feet away from an unprotected edge. The permanently attached metal flags provide additional protection and warning signals. This kit includes six bases and vertical line tubes, 100’ of cable, and laser-cut warning flags. Tie Down Safety maintains high standards and quality control through quality raw materials and components made in the USA.
