Anti-theft devices for catalytic converters are designed to deter theft through various mechanisms. Some common strategies include:
1. Cage or Shield: These are metal cages or shields that encase the catalytic converter, making it difficult for thieves to access and remove it. 2. Alarm Systems: These systems trigger an alarm if tampering is detected, alerting the vehicle owner and scaring off potential thieves. 3. Identification Marking: Marking the catalytic converter with a unique identification number or installing a tracking device can help in recovery if it is stolen.
