Warning Line Systems Protecting Rooftop Workers from a hazard

A roof delineator system is used as a bumpline on a roof where access is required ; however close access to the roof-edge itself is not. The fall protection warning line keeps roof personnel from getting close enough to an edge where they would be at risk of a fall. As a result, you can potentially avoid having to install a guardrail, making the RoofLine series a more cost-effective safety solution.

Self Ballasted Warning Line System

If looking for a warning system that alerts roof personnel of a potential hazard approaching, the RoofLine solution may be your best option. It is often used to create a safe perimeter around a working area or skylight that is over 6 feet away from the roof’s edge. This system can also be used in conjunction with our array of guardrail solutions.
