KATTGUARD® Warning Line Systems

FIXFAST USA WL32 Warning Line on a roof

Provides High Visual Warning of a Fall Hazard

The KATTGUARD permanent warning line system provides high visual warning of a fall hazard. The Aluminum posts are positioned every 15 to 30 feet and connected with plastic coated galvanized aircraft cable with aluminum danger pennants every 6 feet.


Permanent Warning Line System


For metal decks and standing seam roofs, we offer an aluminum base that spans multiple roof profiles and can either be fastened down with self-sealing rivets, or clamped with non-penetrating seam clamps. Both mounting types offer the same OSHA compliance and high visual awareness to ensure people are kept a safe distance from fall hazards.


Various mounting options are available to suit different roof types and profiles. Our KATTGUARD freestanding warning line for membrane and built-up roofs, features a galvanized steel weighted base that is completely non-penetrating and sits on top of the roofing membrane.

Combined Efforts

KATTGUARD VISUAL can be combined with KATTGUARD guardrail to create an OSHA compliant roof safety system. Guardrail can be installed in high traffic areas, access points, and other fall hazard areas and warning line can be located in the low traffic and low-risk areas to form a controlled access zone. With larger facilities, this combination can seriously reduce overall costs, yet still provide the safety that is required.
