This unique rope safety system uses a prusik knot that has been used by mountain climbers for years to help keep them safe while they climb a vertical rope. We use the same concept to make sure hunters stay safe while climbing up and down from their tree stands. The Prusik knot slides up and down the climbing rope while you ascend and descend and CINCHes tight to stop you if a fall does occur. Stay safe from the moment your feet leave the ground.
