Durable Stainless Steel Construction for Permanent Fall Protection
Crafted from corrosion-resistant stainless steel with high-strength alloy D-rings, these ridge anchors deliver a minimum tensile breaking strength of 5,000 lbs. Despite their heavy-duty rating, each anchor weighs less than one pound (0.9 lbs), making them easy to carry up a ladder. These anchors are fully compliant with OSHA 1910, OSHA 1926 Subpart M, ANSI Z359.1-07, and ANSI A10.32-12 standards, supporting a worker capacity of 130 to 310 lbs including tools.
Low-Profile Design for Asphalt Shingles, Shakes, and Tile
The A6302 features a sleek, discreet profile that integrates seamlessly with roofing structures, minimizing visual impact on high-end residential homes. The unique, staggered pre-drilled hole layout is engineered to reduce potential damage to wood trusses during installation, preserving the roof's structural integrity. This kit includes the required 16d nails to ensure a fast, compliant installation on any wood-framed ridge.

Malta Dynamics A6302 Permanent Roof Anchor FAQ
1. Can the A6302 be installed on top of existing shingles?
No. For a permanent installation, the A6302 must be installed directly onto the wood sheathing and centered over a structural ridge member. You must remove the ridge cap, install the anchor with the provided 16d nails, and then reinstall shingles over the strap to keep it weatherproof.
2. Why is the hole layout "exclusive" compared to other anchors?
The staggered hole pattern prevents the nails from being driven in a straight line along the grain of the wood truss. This reduces the risk of splitting the wood—a common error that compromises anchor strength in residential fall protection.
3. Will these anchors cause the roof to leak?
When installed correctly under the ridge cap, the anchor strap and fasteners are protected from rain. For absolute security, many professionals apply a bead of compatible roofing sealant over the nail heads before covering them with the ridge shingle.
4. Can two workers tie off to the same A6302 anchor?
No. The A6302 is a single-user anchor. Even though there are D-rings at both ends, they are intended for access from either side of the roof slope only. Connecting two workers simultaneously is a dangerous violation of the system's rating.
5. Is the anchor compatible with roof tiles or cedar shakes?
Yes. Its low-profile design allows it to sit flush against the wood deck before tiles or shakes are applied. As long as the ridge member is wood and the anchor is fastened directly into structural framing, it is compatible with most residential materials.
6. What happens if an anchor is involved in a fall arrest?
If the anchor is deployed in a fall, it must be removed from service immediately. Because these are permanent, they must be disabled (cut off) and replaced, and the structural wood ridge must be inspected for damage by a qualified professional.
7. How do I avoid the most common installation mistakes?
- 1. Missing the Truss: The most common failure is nailing only into the plywood sheathing. You must ensure the center nails hit the structural ridge board or truss.
- 2. Using Wrong Fasteners: Never use screws or standard roofing nails. Use only the provided 16d nails to maintain the 5,000-lb rating.
- 3. Off-Center Placement: Ensure the anchor is centered perfectly over the ridge. If it's crooked, the D-rings won't sit properly above the ridge cap shingle.
- 4. Splitting the Wood: If a nail splits the wood truss, the anchor loses its hold. Use the staggered hole pattern to prevent this.
