ART SpiderJack 2.1 Dyneema
The ART SpiderJack 2.1 Dyneema serves as a multifunctional, self-blocking rope control device for ascent and descent on running double rope (MRS). With enough practice the SpiderJack 2.1 will allow the tree climber to perform unique movements for very dynamic and strength saving tree climbing. No conversion is needed for changing from ascent to descent or for one-handed adjustment under load. The Spiderjack 2.1 offers controlled yet smooth swings due to its clever thumb break.
The Dyneema sling is attached on to the body of the device, so a second carabiner can capture the stationary rope termination. The Dyneema Kit allows you to more easily switch to different anchor points while climbing. Before climbing, always verify that the ring of the DyneemaKit is connected onto your carabiner!
Details
- With the patented SpiderJack, unlike with the LockJack, there is no need to change cams for ropes from 11 to 13 mm diameter.
- Extremely smooth rope running even with loads. Once the running rope is pulled from above the device, the SpiderJack turns from its blocking position in the direction of the rope. This enables two-handed as well as single-handed shortening and roping up with loads, even when there is no noteworthy rope weight beneath the device to reinforce the rope as it runs through. Pure Efficiency!
- Ergonomic release handle with rope guide. The ergonomically shaped release handle of the SpiderJack has a guide groove on its interior for redirecting the slack rope. Thus, there is no rope friction in the user’s hand.
- Thumb brake for precise control of speed. With a bit of practice, the unique thumb brake enables precise control of the rope speed. For instance, precision landings from higher speeds become a real treat for professionals. But the thumb brake operates dependably and precisely also in “normal use”. Its brake pad is made of pock wood. This wood has unbeatable friction properties, it does not get hot and is also long-lasting.
- Tip: When using the SpiderJack, the harness should be attached to the roping up eye at a low point. The lower the SpiderJack is positioned beneath the load, the longer and thus more effective is each pull with the arm!
- Warning: The SpiderJack does not have a so-called ”panic safety feature”!
