The AA400T is designed for installation in concrete and masonry. It has been specifically developed for applications in rope access (abseiling) but it can be also used to support a fall arrest load of 15 kN provided a suitable personal shock absorber is used.
The AA400T has been independently tested in accordance with AS/NZS 5532:2025 and verified as a 15 kN rated rope access/ fall arrest anchorage device.
INSTALLATION GUIDE

Loading
360° including tensile loading
Proper installation is crucial for the effectiveness of through-bolt anchors. Important factors include:
- Surface Assessment: Ensuring the concrete or masonry substrate is strong enough to support the anchor.
- Correct Drilling Techniques: Using the appropriate drill bit size and depth to achieve a secure fit.
- Torque Application: Applying the specified torque to ensure the anchor’s holding capacity.
- Rotary Hammer drill
- Masonry Drill Bit 18
- Reo detector
- Spanner
- Bar
- Use Hilti Reo Scan or similar device to avoid drilling the steel reinforcement in concrete.
- Mark the position for hole to be drilled.
- Drill one M18 through hole. Ensure the hole is 90° with the drilled surface.
- Install AA400T with the large (120mm diameter) backing plate on the inside.
- Install an M16 washer and lock nut and tighten fully when installing in concrete. When installing in cavity walls, do not over tighten and use a spacer tube to avoid collapsing the cavity. Ensure minimum of 5 threads are showing when tightened.
Through bolts must be visually inspected upon installation and annually as per AS/NZS 1891.4:2025. Do not proof load – visual inspection only!
Note
The structure must be assessed by a structural engineer unless it is clear to a suitably qualified person that it is capable of withstanding the forces imposed on it during a fall arrest situation and/ or during work positioning.
