Be it a safari or just a weekend getaway, be sure your bags and valuables are secure before checking your luggage in at the airport. Safe Skies™ patented luggage locks are the only brand that meet United States Transportation Security Administration standards, so you won't have to worry about your lock getting clipped off. They incorporate one-of-a-kind technology that is dependable and secure. If you have valuable belongings in your luggage and use a non-TSA-approved lock, airport security has the option to cut it off. If your luggage is secured with one of these locks it will not be clipped. TSA agents have been extensively trained on how to open and relock Safe Skies locks. Normally these locks will be re-locked once the security inspection is complete. However, in the unlikely event that one is clipped or damaged by the TSA during travel, it will be replaced it free of charge. This TSA Luggage Lock has four dials for an extra level of protection. Constructed of lightweight 4-oz. heavy-duty die-cast zinc alloy. This combination lock is resettable. Jumbo dials make it for you to see and operate. Dimensions: 3" x 1-1/4" x .5". Per each.
