Universal roof top anchor for metal, concrete, and wood roofs with 310 lb weight capacity, corrosion-resistant steel construction, and OSHA compliance for secure fall protection.
The 3M™ DBI-SALA® Roof Top Anchor Model 2100133 is a universal anchoring solution designed for metal, concrete, and wood roofs, engineered to provide secure fall protection tie-off points in demanding industrial and construction environments. This premium safety equipment features durable zinc-plated steel construction with corrosion-resistant hardware that withstands harsh working conditions. The anchor accommodates roof ribs ranging from 10-20 inches apart with 1-inch increments, making it suitable for both flat and sloped roof decks up to 3:12 pitch angles.
This roof top anchor is engineered to meet stringent OSHA requirements including 29 CFR 1910.140 and 29 CFR 1926.502 standards, ensuring compliance with occupational safety regulations. The compact, lightweight design features a swiveling tie-off point that provides complete mobility while the load-distributing design protects both the roof structure and the user. Installation is straightforward, accommodating 24 gauge or thicker metal, 5/8-inch wood, and 3,000 PSI concrete roofs using reliable screw-type fastening systems.
The anchor supports a weight capacity of 310 pounds (141 kg) and is compatible with various fall arrest systems including self-retracting lifelines, vertical lifelines, and lanyards. Multi-person use is supported through horizontal lifeline system configurations with multiple fastener options available for enhanced jobsite flexibility. As a permanent, reusable anchorage connector, this product serves as the critical foundation for complete personal fall arrest systems in general industrial, construction, mining, and oil & gas applications.
