The Guardian Fall Protection Polydac Rope Vertical Lifeline Assembly is one of the strongest conventional rope assemblies available today. It is 100% resistant to rot and mildew, even if stored when wet, and has excellent resistance to alkalis and most solvents. It also provides good protection against abrasion, and has a melting point of over 300 degrees. Polydac Rope has a working load elongation of 8%, and absorbs more energy than any other type of rope available on the market—12 times as much as Manila and 50% more than polyester. This vertical lifeline assembly is available in a variety of lengths from 25 to 200 feet (see table below for part numbers specific to different lengths). It also includes an integral shock absorbing device, a positioning device, and an 18 inch extension lanyard.
