The strong NRS Tow Tether, with built-in bungee, is used with the quick-release harnesses on rescue life jackets. The Tow Tether, sometimes called a "cow tail," enhances towing boats in rescue situations. The O-ring includes a hook patch of hook-and-loop material that facilitates centering of the O-ring on vests that have the loop material sewn on in the back. The Tether also has a hook patch on the carabiner end. This mates with a loop piece available on some rescue PFDs, forming a quick-release holder for the carabiner. The NRS Nuq Twist Lock Carabiner prevents accidental snag on brush in the field or with other gear. Tow Tether lengths: 33": Stretched length is 33", unstretched is 19" 53": Stretched length is 53", unstretched is 33" Add 6" to length for carabiner and o-ring
