PEACE OF MIND WITH AN INSPECTION INDICATOR. Know if your luggage has been inspected as soon as you pick it up at the airport with our pop-up inspection indicator. If the TSA has opened your luggage, a button will pop out of the top of the cable lock. You'll know to double check your luggage to make sure nothing has gone missing while you're still at the airport instead of at your hotel or final destination. EASY SET COMBINATION MECHANISM WITH FOUR DIGITS. Setting your combination literally takes less than ten seconds and the use of four digits means that your combination is harder to crack and easier to remember. In addition to this, you can change your combination as many times as you would like. A SECURE LOCK WHICH WORKS WITH NEARLY ANY KIND OF LUGGAGE. The standard size of the steel shackle loop on luggage locks is 21.67mm. We decided to lengthen the shackle on these locks to 25.67mm. This allows them to better fit hard cases such as Pelican or gun cases. EASY TO READ DIALS. SureLock uses a white numeral on a black background for our combination dials. These high contrast dials make reading your combination a breeze. No more squinting or searching for glasses as you try to open your locks. International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
