Travel security is very important. We recommend keeping your belongings secure with three-dial combination luggage locks. We all know that Transportation Security Administration (TSA) baggage screeners can open Travel Sentry™ Certified locks (without damaging them) when necessary for inspection. The SignalSearch TSA Lock® has a red and green indicator function which means that you can also know if your bag has been opened by security personnel. We’re just saying… it’s just nice to know.
