Designed for single ropes between 8 and 13 mm in diameter, the Kong DUCK is the first rope clamp in the world that can work even on flat and tubular webbing 10-15 mm wide (even if they are not homologous for progression).

This innovative winch block has very small dimensions, making it easy to insert even with just one hand. In addition, its large attachment hole allows the rotation of the locking carabiners.

This is a very useful model for reeving, self-rescue, progressions and as a regulator for lanyards or webbing daisy.
