The Lasso Security Cable consists of 2 loops of coated security cable that slip around the ends of your kayak. You then wrap the excess cable around your car rack, a tree, whatever, until it is snug enough that it won't slip off either end of the boat. You then lock the ends together with the integral combination lock. Simply put, this is the best kayak security cable on the market! The vinyl coated aircraft cable is galvanized to resist corrosion and has and integrated tamper proof combination lock. Easy to use, no tools required, this system works well with rooftop racks and comes in a convenient Cordura stuff sack.
