ROSU02 Hinged Steel Roof Anchor, 20-Pack
The Frontline ROSU02 is a hinged steel roof anchor that folds over a wooden beam and turns it into a tie-off point. Two steel flaps with eight fastener holes each wrap the two sides of the member; nails through the holes lock it down, and the 1 in diameter anchorage hole becomes the connection point.
Made from galvanized steel with a powder coated or zinc plated finish and weighing just 1.3 lbs, the ROSU02 held 23 kN for one minute in static strength testing per its spec sheet, and Intertek tested the design to ANSI/ASSP Z359.18-2017 as a Type A anchor on wood substrate. The spec sheet also cites ANSI Z359.1-2007, EN 795:2012 Type A, and OSHA 1926.502 and 1910.140. This listing is the 20-pack: twenty individually packaged anchors in one order, ready to outfit a full crew or a full development.

Who Needs This Product
This product is a hinged anchorage connector for personal fall arrest or restraint systems on wood-framed roofs. Roofers and framers fold it over a structural beam, nail through the pre-punched holes, and tie off to the anchorage hole - an economical anchor that crews deploy by the box. Each worker still needs a full body harness and a compatible connecting device.
Features
Hinged two-flap design
The anchor folds to match the beam, bearing on both sides of the member.
Sixteen fastening points
Eight holes per flap distribute the load into the wood.
1 in anchorage hole
A clean, generous connection point for carabiners and snap hooks.
23 kN static tested
Held 5,100+ lbf for a full minute per the spec sheet test data.
Galvanized steel
Powder coated or zinc plated finish for weather exposure.
Crew-friendly price point
Economical enough to anchor every worker - also sold as a 20-pack.

Typical Applications
How to Install the ROSU02 Hinged Anchor
Follow the manufacturer's manual. The sequence below is an overview only.
- Verify the structure. Have a qualified person confirm the wooden beam can support anchorage loads.
- Inspect the anchor. Check both flaps, the hinge, and the anchorage hole before installation.
- Fold over the beam. Hinge the two flaps over the two sides of the member.
- Fasten. Nail through the pre-punched holes per the Frontline manual pattern.
- Connect. Attach your connecting device through the 1 in anchorage hole and perform a pull test.
- Verify clearance. Confirm fall clearance below the work surface before work begins.
Inspection and Retirement
Inspect before each use, with a documented competent-person inspection at least every 6 months. Pull the equipment from service for any of the conditions below.
- Flaps: bending, cracks, or deformation at the hinge or anchorage hole.
- Finish: corrosion or coating breakdown exposing bare steel.
- Fasteners: correct type and count, fully seated, no withdrawal.
- Structure: splitting, rot, or crushing of the beam at the anchor.
- Markings: labels must be present and legible.
Retire the anchor immediately after any fall arrest event or if any inspection point fails. Destroy retired equipment so it cannot return to service.
