ABSTRACT:
A safety system (10) for protecting workers at high altitudes from falling to the ground is disclosed. The system features a rope grip (12) having a rotably mounted wedge (18) in spaced facing relationship with a retaining member (20). The safety line (14) is jammed between the retaining member and the wedge. The rope grip is able to pass by an anchor (16) by virtue of the fact that the retaining member is held in place by rotating slotted wheels (44 and 46).
