FallTech 7439A20 Ironworker Bolt-On D-Ring Anchor (20-Pack)
The FallTech 7439A20 is a 20-pack of ironworker bolt-on D-ring anchors with a 13/16 in hole, sized for the bolts ironworkers already carry. Each anchor bolts to structural steel through a single hole for a fast, low-profile tie-off point.
This contractor case pack keeps a crew supplied across a project. Each anchor is certified to ANSI Z359.18-2017, rated for 5,000 lb (22.2 kN), for one worker up to 310 lb (ANSI) or 425 lb (OSHA).

Who Needs This Product
This product is a 20-count bulk pack of ironworker bolt-on D-ring anchors for structural steel. Ironworkers bolt each anchor through a single 13/16 in hole to create a tie-off point, then connect an SRL or lanyard. Each is a reusable steel anchor. You still need a certified full-body harness and a compatible connecting device.
