Secure your helmet, suit, tank bag or duffel bags in seconds. Works just like a tape measure but uses a spring retractable 36" coated 2.5mm steel cable and resettable three dial combination. Small and light in your shirt pocket but strong enough to discourage bad guys. Locks solid to any length. Lets you relax when seated at some restaurant where you can’t keep an eye on your bike.
