Travel Sentry Approved locks are designed specifically to keep your belongings secure while still allowing the Transportation Security Administration (TSA) to open your luggage at the airport without destroying the lock during their screenings. Featuring a resettable 3-dial combination, this lock is easy to set with Lewis N. Clark's step-by-step written and video instructions making it keys-free, and one less thing to remember. The flexibility of the 70mm steel cable will ensure that it doesn t break when it s going through the conveyor belts at security checkpoints or when baggage handlers are loading and unloading your belongings from airplanes. This combination lock can be also be used on lockers at hostels, gyms, water parks, etc.
