FallTech 7431 Twin-D Permanent Roof Anchor for Wood
The FallTech 7431 Twin-D Permanent Roof Anchor installs permanently on a wood roof and provides two D-rings, so it can serve two tie-off points or pass a horizontal lifeline through for continuous protection. It stays with the building for ongoing access.
It is certified to ANSI Z359.1-2007, rated to a 5,000 lb anchorage requirement, for one worker up to 310 lb (ANSI) or 425 lb (OSHA).

Who Needs This Product
This product is a permanent twin-D roof anchor, the anchorage component of a personal fall arrest system for wood roofs. Builders install it to give a permanent tie-off point with two D-rings, useful for a lifeline pass-through or two connections, then a worker connects an SRL or lanyard. You still need a certified full-body harness and a compatible connecting device.
