摘要
A rappel tool for use in conjunction with rappel rope, the tool comprising a generally rectangularly-shaped and substantially planar rigid body having first and second side edges and first and second end edges. A first opening extends through the body and is proximate and spaced from the first end edge and is spaced from the first and second side edges. A second opening extends through the body and is proximate and spaced from the second end edge and is spaced from the first and second side edges. A third opening extends through the body and is disposed between the first and second openings and is spaced from the first and second side edges. Each of the openings is of sufficient size to permit passage therethrough of a plurality of rappel ropes of a diameter of no more than about nine millimeters.
