ART LockJack2 Basic

Rope control device | 23 kN | alu | for ropes Ø 11–13 mm | EN 358

The LockJack offers every climber, beginner or pro, a safe, dynamic and energy saving climbing in trees. Using footlock technique or foot ascenders the LockJack always allows for elegant ascent on the climbing line or along the trunk. In the tree crown a one-handed pull on the rope is enough to manage a permanently tight rope. While ascending on a rope with no load climbers easily feed the rope from top with one hand through the rope duct.
