ART LockJack Sport

The Lockjack Sport with Swivel offers unique climbing opportunities. Using footlock technique or jammers allows an elegant ascent either on free hanging rope or on the trunk. When climbing in the tree crown, one-handed tugging on the line is sufficient to grant a permanently taut rope. Further advantages are: no need to take in rope unlike with techniques using knots thus interrupting the climbing motion, no melting of knot material when abseiling swiftly.

The Lockjack Sport Swivel helps to compensate twisting lines and body movements for keeping the Lockjack in the optimum handling position at all times. Thus, even more climbing convenience is achieved.
