| Understanding Vault Lock Configurations |
| Indirect Drives - Some vault locks are
direct drive. The dial spindle enters the lock case and attaches
directly to the drive cam. Others use indirect drive, where
the dial spindle attaches to a drive gear located outside the
lock case. This gear drives two other gears in turn to transmit
motion to the lock's drive cam. An indirect drive negates a
punching attack. An indirect drive can be configured at the
end of the lock case opposite the bolt, below the lock case,
or at the top of the lock case. The drawings to the right illustrate
the three indirect drive configurations. |

|
| Bolt Variations - Vault locks can be equipped
with one of five different bolts. The three extension models
are designed to attach directly to boltwork or a blocking bar.
The standard square bolt is used to block moving boltwork. The
roller bolt, seldom used today, opens to provide a path into
the lock case into which a boltwork extension can move. The
five models are illustrated to the right. |
