This keeps the system compact and efficient.\u003c\/p\u003e\n\n\u003ch2\u003eSmooth Rope Running Under Load\u003c\/h2\u003e\n\u003cp\u003eWhen the running rope is pulled from above the device, the SpiderJack turns from its blocking position towards the rope. This supports smooth rope movement, even when loaded and when there is little rope weight beneath the device.\u003c\/p\u003e\n\n\u003ch2\u003eErgonomic Release Handle\u003c\/h2\u003e\n\u003cp\u003eThe ergonomic release handle includes an internal guide groove for redirecting slack rope. This helps prevent rope friction in the user’s hand and supports smoother operation during climbing.\u003c\/p\u003e\n\n\u003ch2\u003ePrecise Thumb Brake Control\u003c\/h2\u003e\n\u003cp\u003eThe unique thumb brake allows precise rope speed control. The brake pad is made from pock wood, chosen for its excellent friction properties, heat resistance and long-lasting performance.\u003c\/p\u003e\n\n\u003ch2\u003eImportant Use Notice\u003c\/h2\u003e\n\u003cp\u003eThe ART SpiderJack 2.1 does not have a panic safety feature. Users must strictly follow the manufacturer’s manual, especially during training and the learning phase. This device is best suited to trained and experienced climbers.\u003c\/p\u003e\n\n\u003ch2\u003eClimbing Tip\u003c\/h2\u003e\n\u003cp\u003eWhen 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 more effective each arm pull becomes.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;
