Keep the items inside your luggage safe with the Voltage Valet 3 Dial TSA Indicator Combination Lock. With this lock, you set your own combination and can reset it for added security. Travel Sentry® approved, airline check-in personnel and the TSA have been trained to recognize this lock and know that your luggage can remain locked during check-in. The TSA Search Indicator lets you know when your lock has been opened by the TSA (Transportation Security Administration).
