Which type of lock is designed with cross-bores and edge-bores for installation in a door?

Bored Lock
Mortise Lock
Deadlock
Surface-Mounted Lock

The correct answer is: Bored Lock

The type of lock designed with cross-bores and edge-bores for installation in a door is referred to as a bored lock. Bored locks are specifically created to be installed in doors that have a cylindrical hole through the face (cross-bore) and a smaller hole on the edge for the latch or bolt mechanism (edge-bore). This design allows for a straightforward installation process, as the lock is placed directly into the drilled holes of the door. In contrast, mortise locks typically require a rectangular pocket to be cut into the edge of the door, which involves more complex installation that is not solely reliant on simple cross and edge bores. Deadlocks are typically standalone locking mechanisms that focus on security and do not inherently feature a built-in mechanism for cross-bores or edge-bores. Surface-mounted locks, as the name suggests, are mounted on the surface of the door rather than being embedded, which eliminates the necessity for cross-bores and edge-bores altogether. Understanding the unique installation requirements of these types of locks is essential for proper locksmith practice.
