<p>It is described a belaying device for blocking a rope comprising a main body formed by two flat plates constrained one to each other preferably according to two parallel planes by means of a plurality of spacing pins. The rope is inserted inside the device body further comprising a carabiner attached to the main body by passing through an opening on the device body. The carabiner allows the belaying device to be constrained to an user, or an anchorage point, and it is movable at the opening between a non-blocking position of the rope, that is the condition of normal use, and an emergency position wherein the rope is blocked, and vice versa.</p> |
