A carabiner is provided with a generally C-shaped body that includes an elongated spine, an upper arm, and an elongated lower arm that is fixed in position with respect to the spine. First and second free ends of the C-shaped body are separated by a gap that may be selectively opened and closed by a gate, positioned generally opposite the spine. The lower arm is provided with a cross-sectional diameter that is larger than a cross-sectional diameter of the spine. Running grooves may be formed into the lower arm to receive lengths of rope in various positions. The lower arm may be formed to be hollow to assist in heat dissipation.
