1. Reliable Dual Braking System: The ratchetresistant double swivels, included in all cable models, minimize twisting of the lifeline during use. The fall protection set can quickly arrest and lock falling objects within a limited distance (≤ 0.2 m/8 inches), reducing injuries caused by acceleration and impact forces. 2. SelfLocking Hook: The selflocking hook securely fastens the height safety device to the anchor point. 3. AviationGrade Braided Wire Rope: The twistresistant multistrand steel cable provides higher tensile strength. (Load capacity: 150 kg/330 lbs. Wire rope diameter: 3 mm.) (Load capacity: 300 kg/661 lbs. Wire rope diameter: 5 mm.) 4. LongTerm Durability: The aluminum alloy inner shell and plastic outer shell offer dual protection for internal components. The nylon rope is wearresistant and heatresistant. The alloy steel Dring ensures a secure connection with the outer shell. The shockabsorbing black rubber cushion and spring provide double padding to protect the rope and minimize damage to the outer shell.
