Watch this overview of the A6300 Series construction, showcasing the heavy-duty galvanized finish and round-post design for easy flashing.
Heavy-Duty Post Construction and Galvanized Steel Durability
The Malta Dynamics A6300 is constructed from hot-dipped galvanized steel, ensuring long-lasting performance and maximum resistance to harsh environmental conditions. This fixed post roof anchor is designed for life-of-the-building applications, providing a sturdy and secure attachment point that meets rigorous safety standards, including ANSI Z359.1-2007 and IWCA I-14.1.
Versatile Installation on Steel and Concrete Substrates
The A6300 offers maximum reliability when secured to structural steel or concrete. The post is designed to extend beyond the insulation and roofing membrane, making the attachment point easily accessible for maintenance crews and window washers. Its round post design is compatible with most standard off-the-shelf flashing kits, ensuring a watertight seal. For detailed fastener requirements, refer to the Malta Dynamics Roof Anchor Instruction Manual.

Malta Dynamics A6300 12-inch Anchor Post FAQ
1. Can the A6300 be installed on a wood deck?
No. The A6300 is specifically engineered for structural steel or concrete substrates. It requires a heavy-duty connection to the building's skeleton to meet the 5,000-lb static load requirement. For wood deck applications, please contact us for compatible specialized anchors.
2. How do I choose between the 12-inch and 18-inch models?
Selection depends on your roof's construction and the anchors' primary purpose. Keep in mind that taller posts assert more leverage against the mounting surface. Also, tie-off height can be a factor in fall distance calculations.
3. Is this anchor suitable for window washing applications?
Yes. The A6300 meets the IWCA I-14.1 standard for window cleaning safety. It is a popular choice for building owners who need permanent, compliant tie-off points for exterior building maintenance.
4. What type of flashing should be used with the round post?
Because the A6300 uses a standard round post design, it is compatible with most "off-the-shelf" cone or deck-flange flashing kits from major roofing manufacturers. This simplifies the roofing contractor's job and ensures a weatherproof finish.
5. Does this anchor prevent thermal bridging?
The A6300 is a hollow, galvanized steel post. For high-efficiency "green" buildings, we recommend filling the post with spray foam or a thermal break material during installation to minimize heat transfer from the building interior to the roof surface.
6. How many fasteners are required for installation?
The base plate features four holes. For steel substrates, typically 5/8-inch Grade 5 bolts with backer plates are used. For concrete, 5/8-inch adhesive or mechanical anchors are required. Always follow the specific bolt pattern provided in the Malta Instruction Manual above.
7. How do I maintain compliance after installation?
- Annual Inspection: OSHA and ANSI require these anchors to be inspected every 12 months by a Competent Person.
- Inspection Log: Use our Interactive OSHA Inspection Form to document the condition of the eyelet, the integrity of the flashing, and any signs of substrate movement.
- Post-Fall: If an anchor is involved in a fall, it must be removed from service and the substrate must be inspected for structural damage.
