THE BORDO CLASSIC AS A COMBINATION LOCK Goodbye keys: All you have to do is memorise a four-digit numerical code and unlock your BORDO™ 6000C. The BORDO™ 6000 has become a real classic over many years - the clever design has won friends all over the world with its high level of security, flexibility and compact size. The 5 mm bars connected with specially designed rivets can be folded like a folding rule. This makes it particularly convenient to transport. The BORDO™ 6000C adds another member to the BORDO™ 6000 family. The C in the product name indicates that this is a combo lock with code. Is there need to worry that the numbers might wear off or fade over time? Not at all - the numbers are not printed. Instead, we produce the code dials from two durable components that guarantee long-term readability.
