The entire system comes pre-rigged in a portable tactical leg bag, ready for immediate use, ensuring components remain integrated and preventing loss.\u003c\/p\u003e\n\u003cp\u003eThe core features a patented eccentric cam mechanical self-locking device that automatically locks to prevent rope slippage during hauling. It includes a \"Dead-man's brake\" for controlled descent and instant stopping upon release. The foldable release handle supports both left and right-hand orientation and remote tether release. The pulleys are equipped with 360° swivels and sealed ball bearings, effectively eliminating rope twisting and tangling during parallel operation, while achieving a mechanical efficiency of over 90%.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cp\u003e\u003cb\u003eIntegrated, Ready-to-Use (includes carry leg bag)\u003c\/b\u003e: The entire system is pre-rigged and tested;
