ART Lockjack Sport 2 with Swivel
Shipping:Calculated at Checkout
The Lockjack is an efficient and easy-to-handle ascender and descender, invented by Hubert Kowalewski to assist tree climbers around the world.
The latest version incorporates the new popular Swivel design, allowing the Lockjack to compensate for twists and turns of rope and the climber.
The ART Lock Jack 2 works just like a climbers friction hitch by pinching the line when weight is applied. It requires only a few feet of rope weight before it starts pulling through on its own, always stays close to the harness and has low profile design.
