What Is a Chubb lock?

Chubb was a manufacturer of locks. The Chubb brand has recently been incorporated with Yale locks and Union locks as they are all owned by the same company, Assa Abloy. Chubb made rim locks, deadlocks, window locks and other secondary security products like key operated locks, door chains etc. People often call a mortice deadlock a Chubb lock. A mortice deadlock is a lock which is morticed, cut into, the edge of the door and is operated by a key from both sides. When you turn the key to lock the lock a deadbolt is thrown and engages in the strike plate which is fitted to the door frame. Once the bolt has been thrown it can not be pushed back into the lock with your finger unlike a latch.
