Super Anchor Flex Chain Temporary and Reusable Roof Anchor
The Super Anchor Flex Chain is a temporary and reusable roof anchor that installs on wood framed structures with the factory supplied nails or screws. The anchor legs are heavy duty 1/4 inch zinc plated steel, and a chain with a 3 inch diameter sliding connector O-ring provides the tie-off point. A 6mm rubber flex band lets the anchor adjust to the roof pitch.
The Flex Chain can be used as a single person anchor or as an anchorage point in a horizontal lifeline system with Super Anchor 30 degree fixed length cables. It ships with two fastener options, 12 each 16d duplex nails and 6 each 3-1/2 inch WS hex head screws, and it meets ANSI Z359.12-09 and CSA Z259.12-11 with a 5,000 pound minimum tensile strength.
Who Needs This Product

- Adjust the pitch. Let the rubber flex band conform the anchor to the roof pitch.
- Connect. Attach a harness and energy-absorbing device to the sliding O-ring, or rig a 30 degree HLL cable.
- Verify. Confirm the anchor is secure and confirm fall clearance before use.
Inspection and Retirement
Inspect before each use, with a documented competent-person inspection at least annually. Remove the product from service for any condition below.
