2815 Retro-Fit Anchor for Existing Roofs, 4-Pack
The Super Anchor 2815 Retro-Fit is a 430 stainless steel retrofit roof anchor with a dacromet coated, stamped D-ring and a 5,000 lb minimum tensile strength. The 13 inch leg fastens to a top chord with 8 Super Anchor supplied 3 inch stainless spiral nails or bugle head screws, under or over the roofing, and the low profile D-ring stays exposed for tie-off. This listing is a pack.
Fall arrest and fall restraint for one worker at 310 lb including tools, with a 6 ft maximum free fall on slopes to 12/12. The 13 inch leg reaches under existing shingle courses so the anchor retrofits onto finished roofs without tearing off roofing. Compliant with OSHA 1926.502 and ANSI Z359.18-17 Type A.
Who Needs This Product
RS anchors are for roofers, maintenance crews, and building owners adding permanent tie-off points to roofs that are already finished: retrofit installs on existing shingle, tile, and metal-decked buildings without tear-off. Each worker wears a full body harness with a personal energy absorber and connects a lifeline or SRL-LE to the exposed D-ring. Anchors space a maximum of 8 ft on center and a minimum of 6 ft from gable edges, and areas outside the 30 degree arrest zone rig as fall restraint. RS anchors are not for window washing, horizontal lifelines, work positioning, scaffolding, hoisting, or lifting.

Reverse and side loads pull fasteners out. Fasteners may unzip when loaded opposite or across the slope, in a free fall, from static loading, or on slopes over 12/12. Load the anchor downslope of vertical center only, space multiple anchors correctly to avoid side loading, and never exceed a 30 degree angle off vertical center in fall arrest. Sheathing must be installed before the anchor is used for fall protection.

Typical Applications
Installation Overview
Full figures, fastener tables, and spacing rules are in the 2025 RS Series manual linked below. The basics:
- Install anchors at the ridge or in the field a minimum of 6 ft from gable edges or free fall hazards, spaced a maximum of 8 ft on center or per the job specific plan.
- Position the anchor leg over a top chord center with the fastener holes aligned per the manual figures, D-ring downslope.
- Drive all 8 Super Anchor supplied fasteners: 3 inch stainless spiral nails, or bugle head screws with a cordless drill at the lowest torque setting, never by hammering screws.
- Angle the off-center fasteners toward the top chord center, with a minimum 2 inch fastener depth into the chord.
- Lay roofing over the leg with the butyl strip or mastic sealing the penetrations, leaving the D-ring exposed.
- Check the underside of the framing for fastener blow-outs; any blow-out means remove the anchor and relocate it.
- On re-roofs, Table 1 fasteners are specified for a single layer of asphalt roofing with a 2 inch minimum fastener depth; contact Super Anchor for longer fasteners over more than one layer.
Inspection and Retirement
Inspect before installation and each use, with documented annual inspections. Remove the anchor from service when any of the following apply:
- The D-ring or shackle is deformed.
- Fasteners are missing or show blow-outs on the underside of the framing; remove the anchor and relocate it.
- Screws were installed by hammering or fasteners were reused.
- The anchor was subjected to a free fall.
- The PID label is missing or illegible.
Tag anchors removed from service to prevent further use until inspected by a qualified or competent person.
