Abstract: In some embodiments, a lifeline comprises an anchor arranged to support a cable and a shuttle arranged to move along a length of the cable. The anchor comprises a body portion and a cable engaging portion. The body portion comprises a thickness. The shuttle comprises a first end and a second end. A cavity extends from the first end to the second end and a slot extends from the first end to the second end. The cable extends through the cavity. A width of the slot is greater than the thickness of the body portion. The width of the slot is less than a cross-sectional size of the cable.

Abstract: In at least one embodiment, a rooftop rigging support system mounts to a roof a building for suspending a load under an eave of the building. In some embodiments, the rooftop rigging support system comprises an arm that extends outward over the eave and then back inward underneath the eave. In some embodiments, the arm is a generally rigid, non-articulating structure. In some embodiments, the arm can be manually pivoted between a deployed position reaching under the eave and a withdrawn position extending above the roof.
