    Abstract: A fall protection device that includes at least a pair of lifeline anchors that are affixed to a wall frame before the frame is tilted up into place. The anchors include a base body that extends outward so that the device can clear the roof overhang so that it can remain in place throughout the construction of the roof. Support members provide sufficient rigidity so that the device has the requisite pull resistance to meet all applicable regulations. A lifeline mount arm is mounted on an upward extension of a base body, and the lifeline is secured between a pair of mount arms.
