    Abstract: A rope anchor which provides a means for a climber to lift a payload is disclosed. The rope anchor has a means for fixing its height in relation to the object being climbed and a v-shaped slot oriented vertically and having its wider end opened upward. A rope being used to lift the payload may be wedged in the slot for anchoring and removed, adjusted, and re-anchored to lift the payload. A hole through the rope anchor allows a light pulley system to be used as well. The rope in the pulley system is then anchored in the v-shaped slot as the payload is hoisted aloft.
