Flying the friendly skies just got safer with this TSA-approved lock from Lewis N. Clark. They call it a triple security padlock because it secures your zipper pulls. It allows you to secure the bag's handle to those zipper pulls. It even lets you secure the case to a fixed object. This Lewis N. Clark lockdown triple protection is also supported by a 3-dial numbered combination lock. Set each number of the combo yourself and reset at will. The result is that your bag becomes the most difficult one to access. This unique lock has a combination square ABS housing. The housing contains two coated, double-braided, stainless steel cables that stick out of it. Each cable is approximately .5 inches thick. Both cables are in loop form, with one being larger than the other. The 70 mm (approximate 2.75 inches) double cables are long enough to accommodate large latch hooks. They can also accommodate zippers with large pull tabs, yet they're short enough to prevent unwanted access. There are two loops of cable on these padlocks to provide maximum protection. Wrap the large TSA cable lock loop around the luggage's handle and attach the opposite loop to a zipper. This ensures your baggage stays closed. Or while you're still in the airport checking in, attach one of the cables to a cart or to the metal leg of your chair at the waiting gate. This will ensure no one takes off with your belongings while your attention is elsewhere. The flexible cables prevent the abuse often caused by baggage handling equipment. The TSA approves of these types of padlocks. That's because they can still scan and verify bags without any obstacles in the way. It's designed to allow TSA officials to open your luggage during a screening. As key-free combination locks, no keys are necessary to search them. This also means there are no keys to lose. The keyhole visible on the underside of the base of the locks is meant for airport personnel. This allows them to check the luggage for a screening without damaging the lock. Furthermore, meddlers are not able to break this travel lock. That's because the square is constructed of cast zinc alloy. The metal body dimensions are approximately 6 inches by 1.8 inches by 5 inches. The linear dimensions are 8.3 inches. For additional durability, this item is also made of thermoplastic rubber materials. These locks come with a full set of printed and video instructions.
