TSA locks are a must for travellers heading to the USA or for those who are travelling through American airports during their gap year. TSA stands for Transportation Security Administration, who have authority over the security of the travelling public in the USA. Should your backpack or travel bag need to be inspected a TSA lock enables the TSA to open the lock without needing your key or combination. If your bag has a lock that isn't TSA approved, it may be broken off by force. Our TSA locks come in both key lock and combination options and we also have TSA cable lock available.
