HelmetLok

HELMETLOK is a carabiner-style lock, with a 4 digit programmable locking mechanism, designed to lock your helmet to your bike.  Simply open the lock, slip the carabiner through your helmet's D-Shackle, attach it to your bike and lock it!  Unlike a conventional carabiner, when the locking arm is open, it pivots outwards. This allows you to attach it to large diameter handlebars, bike frames, gear racks and grab rails, infact it will fit around anything with a 1.5" diameter.

The 4 digit locking mechanism is made from weather resistant zinc alloy and to protect your bike, the aluminium carabiner is covered with a protective plastic coating. 

Since the HelmetLok is not permanently mounted to your frame, you are free to attach your helmet to any suitable place on your bike. Small and compact enough to fit in your pocket or on your belt loop, why be weighed down carrying your helmet around! Use the simple-to-operate HELMETLOK to secure your helmet to any part of your bike and enjoy the security and freedom of HelmetLok.
