TSA APPROVED: This luggage lock is accepted by TSA, allowing TSA inspectors to unlock luggage with an official security screening key. With this suitcase combination lock, you must relock it before removing the key, ensuring your belongings remain protected. If the lock has been opened, a red indicator will pop up to alert you when you retrieve your bag at the airport. EASY TO USE: Code setting is simple with the flip-and-set button located on the bottom. Refer to the packaging for instructions. High-contrast white numbers on black dials make reading the code easy. Features an advanced dampening mechanism that clicks into place with each dial to improve alignment accuracy. Designed for ease of use by travelers of all ages. SAFE & ROBUST: The 4-digit combination offers 10,000 possible codes, providing greater security than a 3-digit lock. Constructed from high-strength zinc alloy, this TSA luggage lock is built to withstand tough travel conditions. The slide-open design is durable and resistant to tampering and forced entry. FLEXIBLE CABLE: The flexible steel cable fits through standard zippers on suitcases, backpacks, duffel bags, and briefcases. At 5.5 inches long, the reinforced cable can secure 2-3 sets of zippers simultaneously, helping protect the entire bag. Ideal for travel, gym lockers, school lockers, drawers, toolboxes, and closets.
