This sealed retractable fall arrester is specifically designed for use in high-contamination or corrosive environments. Its fully sealed construction effectively prevents dust, moisture, grease, and chemicals from entering the housing, protecting the internal braking system and other critical components.The high-grade aluminum alloy housing provides excellent resistance to corrosion and wear, ensuring long-term durability and reliability. The 4.8 mm high-strength steel cable delivers outstanding tensile performance and can withstand the extreme forces generated during a fall. A 360°rotating swivel hook prevents cable twisting and enhances operational exibility.
