Secures your kayak or canoe to your vehicle. Simply put the loop end through a secure place on your canoe/kayak, wrap around your locked roof rack. Then put the ball end through the loop and pull the thing tight. Then either open your trunk or door and carefully put the ball inside your vehicle, finally close trunk or door and lock your vehicle. A determined thief will have tools to remove the cable, but the Kayak Lock is the best deterrent for the opportunist thief.
