Super Anchor 2816 RS-20 Permanent Roof Anchor – 3-Pack Stainless Steel
The Super Anchor 2816 RS-20 Roof Anchor is a versatile, permanent fall-protection solution engineered for tile, slate, wood-shake, and asphalt roofing systems. Featuring a 20-inch stainless steel strap, this anchor allows for a customizable D-ring reveal to match the specific thickness of various roofing profiles. Its flexible design curves over the roof surface for a low-profile installation, providing a secure, 5,000-lb-rated tie-off point for 2026 safety compliance. For standard asphalt shingle projects, we also carry the Super Anchor 2815 Retro-Fit Anchor.

Superior Safety and Environmental Durability
The RS-20 is fabricated from 20-gauge 430 stainless steel to ensure long-term corrosion resistance in harsh outdoor environments. Each anchor uses a stamped Dacromet- or zinc-plated steel D-ring, providing a robust connection point for fall-arrest and fall-restraint applications. The inclusion of factory-supplied butyl flashing strips creates a gasketed, waterproof seal upon installation, protecting the roof deck from moisture intrusion without the need for secondary lead or aluminum flashing kits.
Versatile Installation for Tile and Slate Profiles
Designed specifically for the unique geometry of flat, Roma, and S-type tile roofs, the RS-20 installs seamlessly during new construction or as a retrofit. The 20-inch strap length provides sufficient reach to secure the anchor to a structural ridge beam or rafter while allowing the D-ring to emerge from beneath the last course of roofing material. Each unit is paintable to match the roof's color, making the safety hardware nearly invisible from the ground while remaining fully compliant with OSHA 1926:502 and ANSI Z359.18 Type D standards.

Super Anchor 2816 RS-20 FAQ
1. When should I choose the RS-20 over the RS-10 model?
The Super Anchor 2816 (RS-20) features a 20-inch strap, providing 11.5 inches more reach than the RS-10. This is necessary for tile or slate roofs where a longer strap is required to reach the structural ridge beam while allowing the D-ring to remain accessible at the edge of the roofing material.
2. Is the butyl flashing included in the 3-pack?
Yes. Each kit includes the necessary butyl flashing strips. When installing permanently, the butyl should be applied between the anchor strap and the structural member to ensure a watertight seal around the fasteners.
3. Can this anchor be installed on a finished roof?
Yes, the RS-20 is frequently used as a retrofit anchor. For tile roofs, you will need to temporarily lift or remove a few tiles to secure the strap to the rafter or ridge beam, then reinstall the tiles over the strap.
4. What is the benefit of the 430 Stainless Steel construction?
Unlike standard galvanized steel which can rust over decades, 430 stainless steel provides exceptional durability against the elements. This ensures the anchor remains structurally sound for the entire service life of your roof.
5. Does this anchor support more than one user?
No. The RS-20 is a single-user fall arrest anchor point. Connecting multiple users to a single D-ring is a violation of OSHA safety standards and could lead to structural failure during a fall event.
6. Can I install this on a standing seam metal roof?
While it can be installed on wood-framed structures with metal panels, we recommend our specialized Standing Seam Roof Anchors to avoid making penetrations in the metal surface.
7. How do I avoid common mistakes during installation?
- 1. Rafter Penetration: Ensure all fasteners penetrate into a structural rafter or ridge beam. Nailing into the plywood sheathing alone will not support a 5,000 lb load.
- 2. Strap Orientation: The strap should be pulled taut and follow the pitch of the roof to prevent unnecessary leverage on the nails during a fall.
- 3. Ridge Cap Clearance: Ensure the ridge cap does not pinch or sharp-edge the strap; a small amount of clearance is required for the strap to curve naturally over the ridge.
