Four Layers of Protection. 1. The Column Lock’s patented Ignition Bracket extends through the steering wheel to prevent thieves from turning the wheel. 2. Once secured, the Ignition Bracket also covers the vehicle’s ignition switch, preventing access or tampering. 3. The Column Lock provides a round-the-clock deterrent to thieves with its highly visible coating and markings. 4. The compact, steel main housing wraps the steering column in safety, preventing thieves from stripping and hot-wiring the vehicle.
