Warning Lines | RoofLine Series
Freestanding, easy-to-install system to provide visual warning for workers approaching a hazard
Warning Lines | RoofLine Series is designed for accessing areas of a flat rooftop that are nearing the roof edge (but not within 2m) to provide a visual warning to workers that are approaching a hazard. The system is freestanding, eliminating the need to pierce the roofing membrane which exposes your rooftop to potential leaks.
When a work area is enclosed by properly installed and maintained warning lines, work inside the area can be done without additional fall protection measures.
Warning Lines | RoofLine Series can be customizable depending on rooftop layout and applications, and include:
- 30″ x 30″ Rubber mats to protect roof membrane
- Baseplates – X shaped galvanized steel flat bar
- Posts – 42″ Aluminum post secured to baseplates to support cable and flags
- Coated galvanized steel cable – 500 lbs breaking strength
- Flags – Powder-coated metal flags
