Frontline STW01 Weld-On Anchor | Permanent Steel Fall Protection Anchor Canada
Frontline STW01 Weld-On Anchor — Permanent Steel Anchorage
The Frontline STW01 is a compact, permanent weld-on anchor point built 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 exactly where a permanent connection point is needed — beams, columns, and other steel substrates that can carry the rated load.
Made from ASTM-rated steel and ready to use straight out of the bag once welded by a qualified welder, the STW01 is an economical choice for steel erection, plant maintenance, and any job where a fixed single-point anchor stays with the structure for repeat access.
Key Features
- Compact & lightweight — roughly 1 lb (0.45 kg) and small enough to fit in the palm of your hand for easy handling on the job.
- ASTM-rated steel construction for dependable strength, durability, and corrosion resistance.
- 5,000 lb (22.2 kN) minimum breaking strength — meets the ANSI anchorage requirement for a single worker in fall arrest.
- Welds to most structural steel substrates capable of withstanding the rated load.
- AWS-certified weld quality — manufactured to AWS welding processes for verified compliance and consistency.
- Permanent, low-profile design — stays fixed to the structure for reliable repeat tie-off on the same work area.
- Ready to use straight out of the bag once correctly installed.

Applications
The STW01 is ideal anywhere a permanent anchor point is needed on structural steel:
- Steel erection and ironwork
- Structural steel maintenance and inspection
- Manufacturing, plant, and warehouse tie-off points
- 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 installation instructions, and only onto a steel substrate capable of withstanding the 5,000 lb rated load. Because it is a permanent anchor, plan placement carefully before welding. Always 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.
Standards & Compliance
The Frontline STW01 meets or exceeds ANSI Z359.18 (anchorage connectors), ANSI A10.32, OSHA 1910, and OSHA 1926 when installed and used according to the manufacturer's instructions. It has been tested by an independent third-party lab accredited to ISO/IEC Standard 17025.
Canadian compliance note: The STW01 is certified to ANSI and OSHA standards and is not CSA Z259 certified. Before specifying this anchor for a Canadian worksite, confirm it meets the requirements of your provincial regulations and your authority having jurisdiction (AHJ). If you need a CSA-certified anchor, browse our CSA-rated anchor points or contact us and we'll help you choose the right connection point for your application.
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 systems. It's commonly used in steel erection, plant maintenance, and manufacturing environments.
How much weight can the STW01 hold?
The anchor has a 5,000 lb (22.2 kN) minimum breaking strength — the ANSI requirement for a single worker in fall arrest — and a maximum user capacity of 310 lb (141 kg) including tools.
Who can install a weld-on anchor?
Welding must be performed by an AWS-certified welder following Frontline's instructions, and only onto a steel substrate able to withstand the 5,000 lb rated load. Once correctly welded, the anchor is ready for use.
Is the STW01 CSA certified?
No. The STW01 is certified to ANSI Z359.18, ANSI A10.32, OSHA 1910, and OSHA 1926. It is not CSA Z259 certified. Confirm with your authority having jurisdiction whether ANSI/OSHA-rated anchorage is acceptable for your worksite, or contact us for a CSA-certified alternative.
