Letter-boxes and filing cabinets on your Matrix keys!

Not to mention far greater key security! The flimsy keys & locks supplied with cabinets are cheap-as-chips, and getting worse as the years go on. And they usually have key numbers stamped on the lock, so anyone can go to a locksmith and get a key for your files or mail. Even worse, they have built in generic master keys that operate ALL their locks.

Carbine (an innovative Australian company) have created this replacement lock, which uses a high-quality cylinder that is compatible with Matrix. Control access to your documents today. (And get more keys off your keyring!)
