A6318 Single-Use Roof Anchor 16-Pack
The Malta Dynamics A6318 is a disposable, single-use roof anchor that nails directly through roof sheathing into a truss or rafter to give a roofer a code-compliant tie-off point. Its flexible body bends over the roof peak or lays flat to match the roof pitch, and the removable design leaves no permanent damage when the job is done. This bulk case ships sixteen anchors so a crew is stocked for an entire run of new construction, remodeling, or reroofing.
Each anchor is built from zinc-plated alloy steel, carries a 5,000 lb minimum breaking strength, and supports a single worker from 130 to 310 lb including tools. Every anchor installs with the eight 16d common nails included in the box and is tested to OSHA 1926.502, OSHA 1910.66, and ANSI Z359.18-2017 Type A, backed by a Malta Dynamics Declaration of Conformity with independent ISO 17025 lab testing.
Who Needs This Product
The A6318 is a single-use anchorage connector, the tie-off point of a personal fall arrest system for roofers on wood-framed roofs. It is disposable by design: it nails through previously secured sheathing into a structural truss or rafter, and once installed it is not removed and reused. Each connected worker still needs an ANSI full body harness and a compatible connecting device such as a self-retracting lifeline or a shock-absorbing lanyard that limits free fall. One anchor protects a single worker. The 16-pack keeps a roofing crew supplied across multiple tie-off locations and multiple jobs without reordering between roofs.
Features
Flexible pitch design
The anchor bends over the roof peak or lays flat to match the roof pitch, so one shape works across the whole roof.
Nails included
Each anchor ships with eight 16d common nails and pre-punched attachment holes, so setup is fast with no extra hardware to source.
No permanent damage
The removable single-use design leaves no permanent hole pattern or hardware behind once the anchor is taken down.
Zinc-plated alloy steel
Built from zinc-plated alloy steel for added strength and corrosion resistance through exposure on the roof.
Stocked by the case
Sixteen anchors per case keep a roofing crew supplied across multiple tie-off points and multiple jobs.
Independently verified
Backed by a Malta Dynamics Declaration of Conformity with third-party testing performed under ISO 17025 accreditation.

Single use only, and the structure carries the load. The A6318 is disposable: install it once and never reuse it. It must be nailed through sheathing into a solid structural member such as a truss or rafter, never into sheathing alone, with all eight 16d nails fully driven. A fall protection system is only as strong as its anchor point, so a competent person must verify the structure can support the anchorage load and you must calculate fall clearance before tying off.
Compliance Standards
ANSI Z359.18-2017 Type A
Anchorage connectors standard. The A6318 is tested as a Type A anchorage connector under the ANSI Z359 fall protection code.
OSHA 29 CFR 1926.502
Construction fall protection systems criteria, including anchorage strength requirements for personal fall arrest.
OSHA 29 CFR 1910.66
General industry personal fall arrest anchorage requirements.
ISO 17025 Tested
Conformity verified by an independent third-party laboratory accredited to ISO 17025, documented in the Declaration of Conformity.
Typical Applications
Installation Overview
Install per the Malta Dynamics user instruction manual. The sequence below is an overview only.
- Inspect. Check each anchor body, attachment holes, and the included nails before installing. Use a new anchor for each location.
- Locate a member. Find a structural truss or rafter under the previously secured sheathing, with a minimum 1/2 in nominal plywood; do not attach to sheathing alone.
- Position. Lay the anchor flat to match the pitch, or bend it over the peak, at the location specified in the manual.
- Nail. Drive all eight included 16d common nails through the pre-punched holes into the structural member, fully seated.
- Connect. Clip a shock-absorbing lanyard or self-retracting lifeline that limits free fall to 6 ft, plus an ANSI full body harness, to the anchor. One worker per anchor.
- Verify clearance. Calculate and confirm fall clearance and swing fall below the work surface before work begins.
Inspection and Retirement
Inspect each anchor before installation. Because the A6318 is single use, it is installed once and then retired, never removed and reinstalled. Do not use any anchor showing the conditions below.
- Body: bending beyond the intended pitch shape, cracks, or elongated attachment holes.
- Finish: corrosion beyond surface discoloration on the zinc-plated steel.
- Attachment holes: deformation, tearing, or sharp edges around the punched holes.
- Nails: bent, short, or missing nails; all eight must be present and fully driven.
- Labels: must remain legible and intact.
Retirement triggers: any fall-arrest event, any installed anchor at the end of the job, or any anchor that could not be fully nailed into a structural member. Single-use anchors are removed from service and discarded, never reused on the next roof.
