A lock striker, often referred to as a strike plate, is a critical piece of hardware installed on the door frame that works in conjunction with a door lock to secure the door. It is the component that receives the latch or bolt extending from the lock mechanism in the door.
Understanding the Lock Striker (Strike Plate)
Based on common usage and the provided reference, a lock striker is primarily the strike plate. According to the reference, a strike plate is:
- A piece of hardware that works with a lock to keep a door secure.
- Installed on the door frame.
- Contains a hole which receives the spring-loaded latch or bolt which comes out of the latch or lock.
This means the striker plate provides the receiving point for the moving parts of the lock, allowing the door to stay closed and locked.
How it Works
When you close a door, the spring-loaded latch on the lock (the angled piece) extends into the hole in the strike plate. If the door has a deadbolt, this bolt also extends into a separate, often reinforced, hole in the strike plate when locked. This engagement is what keeps the door held shut within the frame.
Think of it as the "socket" for the lock's "plug".
Key Functions and Importance
The strike plate serves several vital functions:
- Security: It provides a solid point of engagement for the lock's bolt or latch, contributing significantly to the door's security against forced entry.
- Holding the Door Closed: The latch mechanism resting in the strike plate's opening is what keeps the door shut even when it's not locked.
- Door Alignment: A correctly installed strike plate helps ensure the door closes properly and aligns within the frame.
- Frame Protection: It protects the door frame from wear and tear caused by the metal latch or bolt repeatedly striking it.
Types of Strike Plates
Strike plates come in various shapes and sizes depending on the type of lock and door frame. Some common types include:
- Standard Lip Strike: Features a small lip extending from the plate.
- Full Lip Strike: Has a longer lip, often used to bridge a gap between the door and frame.
- T-Strike: Shaped like a 'T', commonly used with some deadbolts.
- Deadbolt Strike: Often larger and more robust, specifically designed to receive a deadbolt.
| Component | Location | Function |
|---|---|---|
| Lock Striker (Strike Plate) | Door Frame | Receives latch/bolt to secure door |
| Lock Body/Latch | Door Edge | Contains the mechanism with latch/bolt |
| Latch/Bolt | Extends from Door | Engages with the strike plate hole/opening |
In summary, the lock striker, or strike plate, is an essential piece of door hardware mounted on the frame that collaborates with the lock on the door to ensure it remains closed and secure.
