Key Considerations
- Shackle Thickness: A thicker shackle usually means a stronger lock. Choose one according to your security needs.
- TSA Approved: TSA-approved locks allow security personnel to open your luggage without damaging the lock during their inspections at airports. It’s especially important for checked luggage.
- Lock Type: Combination locks are convenient for those who don’t want to carry keys, while key locks offer a higher level of security but require you to keep track of keys.
- Size and Compatibility: Ensure the lock size is compatible with your luggage or suitcase zippers. A lock that’s too big may be cumbersome, while one that’s too small may not provide enough security.
