Freestanding Non-Penetrating Warning Line - WL32

Our freestanding warning line for membrane and built-up roofs features a plastic-coated steel weighted base that is completely non-penetrating and sits on top of the roofing membrane. Aluminum posts are placed 15-30 feet apart and connected by a plastic-coated stainless steel cable. Aluminum danger pennants are attached to this cable every 6 feet to make the line more visible.

Various mounting options are available to suit different roof types and profiles. Since the modular system can fit virtually any configuration, you can customize the WL32 warning line system to your specific application
