The self-jamming device allows easy adjustment of the length and tension between the two anchor points (make a mule knot on the GRILLON to lock the anchor). Semi-static rope, resistant to aging and abrasion. Sewn terminations on both ends with plastic sheath to keep the connector in position and protect the rope from abrasion.
