Deadbolt locks are mounted by being installed in a hole cut through the door.
Here's a breakdown of the deadbolt lock mounting process:
-
Hole Preparation: A circular hole is drilled through the door to accommodate the lock cylinder and body. Standard door prep sizes are typically 2 1/8" for the main hole and 1" for the latch.
-
Mortise or Surface Mounting: There are two main types of deadbolts:
- Mortise Deadbolts: These require a rectangular pocket (mortise) to be cut into the edge of the door. The lock mechanism then fits into this pocket.
- Surface-Mounted Deadbolts: (Often found on apartments or older doors). These are mounted to the surface of the door and frame with minimal alteration to the door itself.
-
Cylinder Installation: The cylinder (where the key goes) is inserted through the hole in the door.
-
Bolt Installation: The deadbolt itself is installed in the edge of the door and extends into the door frame.
-
Strike Plate Installation: A strike plate, which contains a hole for the bolt to extend into, is installed on the door frame, aligned with the deadbolt.
-
Securing the Lock: Screws secure the lock components to the door, ensuring a tight and stable fit.
When the deadbolt is extended, it projects into the strike plate on the door frame, providing a secure locking mechanism that resists forced entry. The design ensures that force applied to the end of the deadbolt will not easily retract it, enhancing security.
