Abstract
An apparatus and method for temporarily anchoring a horizontal lifeline to existing rebar extending from concrete. Preferably, two triangular frames are temporarily secured to vertically extending rebar by eight sets of J-bolts and speed nuts. The frames are preferably made of tubular steel, and may be attached to the vertically extending rebar by one workman. Two or more rebar lifeline anchors may be used in combination to secure the ends of a horizontal lifeline. Three or more anchors can be used to secure two or more lifeline that are perpendicular to each other, such as along the outer, leading edges of a construction site.
