Petzl Attache Screw-Lock Bar Carabiner Gray. When used with the removable BAR the pear-shaped ATTACHE carabiner is a versatile tool. It becomes a unidirectional carabiner oriented to load the major axis and maximizing ease of use when belaying or using ropes for glacier travel. It has an H-frame to keep the weight low and the round-stock basket creates a smooth surface for the rope to run over for easier belaying with the VERSO REVERSO or a Munter hitch.
