Frontline Temporary Warning Line Kit — Flat Roof Perimeter Marking (Canada)
WARNING LINE SYSTEMComponent-serviceableMODEL WLS16
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.

Frontline temporary warning line kit questions answered
How far from the edge does a warning line go?
Commonly 2 m (6.5 ft) minimum, but it varies by province and task — check your local OHS regulation (e.g., Ontario O. Reg. 213/91) before layout.
Does the WLS16 replace guardrail or personal fall arrest?
No. A warning line is an administrative control that marks a controlled access zone; where workers go past the line or near the edge, guardrail or personal fall arrest is still required.
Why a steel cable instead of a rope warning line?
Coated steel cable stays taut, survives UV and winter storage, and won’t stretch into a sagging trip line mid-season.
Is the warning-line system CSA certified?
Warning lines are an administrative control under provincial OHS rules, not CSA Z259 certified PPE — confirm setback and flag-spacing against your provincial regulation.
