The KwikSafety TSUNAMI is a 50 ft vertical lifeline assembly for roofing and other fall-arrest work. It uses braided polyamide rope rather than twisted rope, which resists abrasion better and stays more flexible. An alloy steel rope grab slides along the line, and two double-locking snap hooks plus a polyester shock absorber complete the system. It suits one worker up to 310 lb total weight, including tools, and is not for horizontal use. Buyers rate it highly, and the braided rope and smooth rope grab are the features most often singled out.

The KwikSafety TSUNAMI is a 50 ft vertical lifeline assembly for roofing and other fall protection work. The rope is braided yellow and black 100% polyamide, which resists abrasion and stays flexible. It has a hardened plastic thimble. A 100% polyester shock absorber in a PVC cover deploys in the event of a fall.
The assembly has two steel double-locking snap hooks, each with a 5,000 lb limit. An adjustable rope grab is attached and moves along the lifeline. It is not for horizontal use. It works with any fall protection harness, safety lanyard, roof anchor, rope ladder, or anchor with a D-ring.
The lifeline is for one person, up to 310 lbs including tools and equipment. It is tested by a third-party accredited lab and complies with ANSI/ASSE Z359.15-2014. It is intended for uses where OSHA compliance is required, such as roofing, construction, gutter cleaning, inspection and maintenance, wind turbines, communication towers, water tanks and wells, shipyards, and window washing.
