This model stands out in IFAM's TSA range of padlocks, which are special for trips to the US and other countries that use this system for customs in their airports. The TrypLock 4W stands out because it has 4 rollers with 10 digits, which gives it extra security because users can choose their combination from among 10,000 possible variations.
This video shows how to programme the combination for the padlock very easily.
