Eagle Creek's 3-Dial TSA Security Lock is allows you to lock up your baggage to keep your things safe while you travel. The cable allows you to lock multiple bags together or to a stationary object. If it isn't needed, the TSA lock can be used to secure locking zippers closed when you only have one bag. You can have peace of mind while you travel knowing your things are safe and that if TSA needs to inspect your luggage, your bag and lock won't be damaged.
