Frequently asked questions
Is the Frontline Mega Swivel STM58 CSA certified for Canadian jobsites?
No. The Mega Swivel STM58 is certified to ANSI Z359.18 and OSHA 1926.502 — not CSA Z259. Many Canadian sites accept ANSI/OSHA-rated equipment, but confirm with your authority having jurisdiction (AHJ) before use.
How much load does this anchor hold?
It meets the 5,000 lb (22.2 kN) anchorage requirement for a single worker in fall arrest. The supporting structure must also be able to carry the rated load.
Which Mega Swivel STM58 option should I choose?
This listing offers 10K Steel (STM5810K), 316 Stainless 5K (STM585K-SS) and Reinforcement Backing Plate (SWX100N). Pick the option that matches your task and work envelope; they share the same core design and certification.
How often should the anchor be inspected?
Inspect the anchor and your full personal fall arrest system before each use, and remove it from service if you find any deformation, cracking, corrosion or other damage.
