We found a way to make our patented PowerClaw latches even better - they are now lockable! The easy-to-install retrofit kit can be installed on many NANUK cases and adds another layer of security to your case. All our TSA Latches bear the Travel Sentry® Red Diamond logo, which allows security personnel to open your case for inspection when required during travel. Each lock has a special TSA001 to TSA003 code, which is used by the TSA, CATSA and other security agencies to know which secure tool to use to open the lock. *Compatible with NANUK 908 – 918 – 920 – 925 – 933 – 935 – 940 – 945 – 950 – 960 cases.
