Frontline STW01 Weld-On Anchor | Permanent Steel Fall Protection Anchor Canada
PERMANENT WELD-ON ANCHORANSI Z359.18MODEL STW01
The Frontline STW01 is a compact, permanent weld-on anchor point for fall protection on structural steel. Small enough to fit in the palm of your hand yet rated to a 5,000 lb (22.2 kN) minimum breaking strength, it gives your crew a clean, low-profile tie-off on beams, columns and other steel substrates that can carry the rated load.

CERTIFICATION — ANSI Z359.18 · ANSI A10.32 · OSHA 1910 / 1926
Certified and third-party tested (ISO/IEC 17025) to US standards. The STW01 is not CSA Z259 certified — confirm ANSI/OSHA anchorage is accepted by your authority having jurisdiction before specifying it for a Canadian worksite.
Applications
Built for steel erection and ironwork, structural steel maintenance and inspection, manufacturing and warehouse tie-off points, and fixed anchorage for horizontal lifeline terminations and personal fall arrest connections.
Installation & use
The STW01 must be welded to the structure by an AWS-certified welder following Frontline’s instructions, and only onto a steel substrate capable of withstanding the 5,000 lb rated load. Because it is permanent, plan placement carefully before welding. Inspect the anchor and your full personal fall arrest system before each use, and remove from service if any deformation, cracking or weld damage is found.
Frequently asked questions
What is the Frontline STW01 weld-on anchor used for?
It’s a permanent single-point anchor that welds onto structural steel to provide a tie-off point for personal fall arrest or fall restraint — common in steel erection, plant maintenance and manufacturing.
How much load can the STW01 hold?
It has a 5,000 lb (22.2 kN) minimum breaking strength — the ANSI requirement for a single worker in fall arrest — and a 310 lb (141 kg) maximum user capacity including tools.
Who can install a weld-on anchor?
Welding must be done by an AWS-certified welder following Frontline’s instructions, onto a steel substrate able to withstand the 5,000 lb rated load. Once welded, it’s ready to use.
Is the STW01 CSA certified?
No. It’s certified to ANSI Z359.18, ANSI A10.32, OSHA 1910 and 1926 — not CSA Z259. Confirm with your authority having jurisdiction whether ANSI/OSHA anchorage is acceptable, or contact us for a CSA-certified alternative.
