The Lockjack Sport offers every climber, beginner or pro, a safe, dynamic and energy saving climbing in trees but it is more suited for the more advanced climber. Using footlock technique or foot ascenders the Lockjack always allows for the 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 the top with one hand through the rope duct.
Named the Basic version as it does not have a swivel connection to your harness.
Climbing above 20 meters with a Rope guide at the anchor point the climbing line tightens by its own weight alone. That's how smoothly the rope runs through the Lockjack and still, it blocks automatically and safely with any impact.
Please see PDF or manual for recommended carabiner choice.
