Ascenders  

In traditional systems, climbers have to grab hold of the rope and use force to climb a tree. This requires a firm grip and a considerable amount of strength, which makes the task physically exhausting. Ascenders help make this task easier. They have one-way cams that clamp onto a climbing rope securely, giving the climber a good grip and firm leverage.

At Northern Arb, we have different kinds of products like hand, foot, and chest ascenders so you can choose an option that is most suitable for your rig.
