Aluminum combination lock with adjustable code and plastic wheels. No keys, no worries? With our 144 combination lock, definitely! The numerical code can be easily set with 3 or 4 dials depending on the size of the lock, thanks to the extra-large number wheels. Additionally, the numbers are very clearly and durably readable, as they are not painted but instead injected into the number wheels. This ensures they remain visible in the long term.
