Superior Construction and Galvanized Steel Strength
The Malta Dynamics A6301 18-inch Standard Anchor Post is constructed from high-quality hot-dipped galvanized steel, ensuring exceptional durability and long-lasting performance. This taller fixed post roof anchor is suitable for permanent use, providing a robust and secure attachment point that meets stringent safety standards, including ANSI Z359.1-2007 and IWCA I-14.1. At 18 inches tall, this anchor post is ideal for projects requiring a higher attachment point to clear obstructions or deep insulation.
Flexible Installation for Comprehensive Safety
The A6301 offers flexible installation options on structural steel and concrete substrates. This anchor post extends beyond the roofing materials to ensure the attachment point is easily accessible to maintenance workers and window cleaners. It is compatible with retractable lifelines, vertical lifelines, and rope grab units. Refer to the Malta Dynamics Roof Anchor Installation Manual for detailed fastener requirements.

Malta Dynamics A6301 18-inch Anchor Post FAQ
1. Why would I choose the 18-inch post over the 12-inch model?
The 18-inch A6301 is designed for roofs with thick insulation (R-value requirements) or "green roof" assemblies. It ensures the tie-off eyelet remains accessible at least 2 to 4 inches above the finished roof membrane, even when deep layers of polyiso insulation or ballast are used.
2. Can this anchor be used for horizontal lifeline (HLL) systems?
Yes. The A6301 is a common end and intermediate post for permanent horizontal lifelines. However, horizontal lifelines assert significant lateral force. We recommend requesting a Professional Engineering Layout before installing these as part of an HLL system.
3. Is the A6301 compliant for window washing?
Yes. This anchor meets the IWCA I-14.1 standard for window cleaning safety. It provides the 5,000-lb capacity required for building maintenance workers who need a permanent, accessible tie-off point.
4. What type of flashing is required for the 18-inch round post?
The A6301 features a standard round post design, making it compatible with universal cone flashing or deck-flange flashing from all major roofing brands. This ensures a watertight seal regardless of the roofing membrane type.
5. Does the taller post height affect the strength of the anchor?
While the anchor remains rated for a 5,000-lb static load, the 18-inch height does increase the leverage applied to the substrate during a fall. It is critical that the structural steel or concrete it is mounted to is verified by a qualified person to handle these forces.
6. How many fasteners are required for the A6301 base plate?
The base plate is pre-drilled with four holes. For steel, 5/8-inch bolts with backer plates are used; for concrete, 5/8-inch adhesive or mechanical anchors are required. Always follow the torque specs in the manual above.
7. What maintenance is required once installed?
- Annual Inspection: A Competent Person must inspect the anchor, eyelet, and flashing every 12 months.
- Structural Verification: Every 10 years (or per building code), the mounting substrate should be re-evaluated for integrity.
- Inspection Log: Keep a permanent record using our OSHA Anchor Inspection Form.
