No more cut locks! - The USA Travel Security Administration (TSA) has recognized these special indicator locks for use on all airline luggage. Unlike old locks that would be cut off and discarded, these can be opened and then re-locked by TSA Officers. The secret? These combination locks can be opened with a special secured access device carried only by TSA Officers.For added peace of mind a red indicator alerts you if your bag has been searched. The Indicator can be easily reset when you open the lock with your own personal combination.
