Whether you choose a combination padlock or one with a classic key has nothing to do with the quality or the intended use.
However, the selection of padlocks with a classic key is much larger - accordingly, you will find the right lock more quickly here.
However, there are areas of application in which the combination padlock has prevailed. These locks are often used to secure suitcases and luggage. A high-quality luggage lock can only be an advantage here. Particularly practical for air travel, especially to the USA, are the TSA combination locks from BURG-WÄCHTER.
For example, the BURG-WÄCHTER TSA 78 combination security lock. The adjustable combination lock is equipped with three combination wheels. Choose your
personal combination of numbers and secure your luggage and much more - without keys.
Info: TSA locks
These combination locks are specially designed for air travel to the USA. The US security authority TSA can open the lock for inspection purposes. If your suitcase has a lock without TSA, your luggage may be broken into.
