ROPE CLAMPS Alpic Accès Difficiles, Gorges du Borne, France © Petzl / Lafouche 98 Rope clamps are primarily used for progression on ropes and for creating haul systems. Easy to use Optimal grip Rope clamps have to be easy and quick to use, for efficiency during progression, for passing intermediate anchors and for transitioning from ascending to descending. To do this, the rope is grabbed by a retractable spring-loaded cam. When the cam is locked in the open position, the rope channel is clear and thus facilitates the installation of the clamp onto the rope. Petzl's frame-loaded rope clamps are designed to function optimally under any conditions (wet, frozen, dirty ropes, for example). They are therefore equipped with a specific stainless steel cam. Its unique design, the shape of its teeth and its self-cleaning slot allow optimal grip on the rope without damaging it, while reducing the effort required to slide the device up the rope.
