Abstract
A rope guide is provided for use in rope rescues and rope climbing. The guide includes a frame comprised of two legs, pivotally connected at the inner ends so that the outer ends can be adjusted between substantially open and substantially closed positions. A lock pin secures the frame in a selected pivotal position. The mouth of the frame between the outer ends of the legs can be positioned over an object, such as a rail, a building edge, or a rock so as to protect the rope from contact with such objects.
