Frontline Temporary Warning Line Kit — Flat Roof Perimeter Marking (Canada)
Flat roof systemComponent-serviceableWLS16
Define the safe zone on any flat roof with the Frontline WLS16 warning line system. Weighted base, upright with carry handle, and flagged steel cable mark the controlled access zone so crews working back from the edge don't need individual tie-off — and it pairs directly with the Frontline GUS guardrail systems we stock.

COMPLIANCE IN CANADA
Warning lines are an administrative control under provincial OHS rules, not CSA Z259 certified PPE. Verify your province's setback and flag-spacing requirements (e.g., Ontario O. Reg. 213/91) when planning the layout.
Common questions
How far from the edge does the line go?
Commonly 2 m (6.5 ft) minimum, but it varies by province and task — check your local OHS regulation before layout.
Steel cable vs rope warning line?
Coated steel cable stays taut, survives UV and winter storage, and won't stretch into a sagging trip line mid-season.
