Door Strike Plate: What Is It & How Does It Work?
The security of your home relies on several components, and understanding how they work is crucial. A key element in ensuring that security is the door frame, which works in tandem with the locking mechanism. Many homeowners often overlook door hardware such as strike plates. Therefore, let's explore what is a strike plate on a door and how it protects your home from being easily broken into. Understanding its function is vital for ensuring optimal security and peace of mind.

Door Strike Plate: Unveiling Its Function and Importance
This guide explains what a strike plate on a door is, its purpose, and how it works. We'll also touch on different types of strike plates and how to choose the right one.
What is a Strike Plate on a Door?
A strike plate, sometimes called a door strike or strike, is a metal plate installed on the door frame where the latch or bolt from the door's lock mechanism engages. It provides a secure and reinforced point for the door to latch or lock into. Essentially, it's the counterpart to the latch or bolt located on the door itself.
Why is it Important?
- Security: The strike plate reinforces the door frame, making it more resistant to forced entry. Without a strike plate, the latch would engage directly with the relatively soft wood of the door frame, making it much easier to break open.
- Durability: Consistent use of the door latch can wear down the door frame. The strike plate protects the frame from damage, extending the lifespan of both the door and the frame.
- Proper Alignment: The strike plate helps to ensure the door latch or bolt aligns correctly with the opening in the frame. This allows the door to close and lock smoothly.
- Aesthetics: Strike plates often come in different finishes, allowing you to match them to your door hardware and enhance the overall appearance of your door.
How Does a Strike Plate Work?
The strike plate works by providing a sturdy receptacle for the door's latch or bolt. Here's a breakdown of the process:
- Closing the Door: As you close the door, the angled edge of the door latch makes contact with the strike plate.
- Latch Retraction: The angled edge of the strike plate pushes the latch back into the door.
- Latch Engagement: Once the door is fully closed, the latch springs back out and extends into the opening (also called the "mortise") in the strike plate.
- Locking the Door (if applicable): If the door has a deadbolt, turning the key extends the deadbolt into a separate, larger opening in the strike plate.
This simple mechanism provides a secure point of engagement, preventing the door from easily being pushed or pulled open.
Different Types of Strike Plates
Strike plates come in various shapes, sizes, and materials to suit different door types and security needs. Here are some common types:
Lip Strike Plate
- Description: This is the most common type of strike plate. It has a "lip" that extends beyond the edge of the door frame to protect it from damage caused by the door latch.
- Application: Suitable for most standard interior and exterior doors.
Deadbolt Strike Plate
- Description: Designed specifically for use with deadbolt locks. They typically have a larger, reinforced opening to accommodate the larger deadbolt.
- Application: Used on exterior doors and doors requiring a higher level of security.
Full Lip Strike Plate
- Description: A variation of the lip strike plate, where the lip wraps around the entire edge of the door frame.
- Application: Provides maximum protection to the door frame edge.
T-Strike Plate
- Description: Shaped like a "T," this type of strike plate is often used with mortise locks.
- Application: Common in older homes or commercial buildings with mortise locksets.
Adjustable Strike Plate
- Description: Offers adjustability to compensate for slight misalignments between the door and the frame.
- Application: Useful when the door frame is slightly warped or when the door doesn't close perfectly.
The table below summarizes the different strike plate types:
| Strike Plate Type | Description | Application |
|---|---|---|
| Lip Strike Plate | Standard strike plate with a lip extending beyond the door frame edge. | Most interior and exterior doors. |
| Deadbolt Strike Plate | Reinforced strike plate with a larger opening for deadbolts. | Exterior doors requiring enhanced security. |
| Full Lip Strike Plate | Lip wraps around the entire edge of the door frame. | Provides maximum protection to the door frame edge. |
| T-Strike Plate | Shaped like a "T"; used with mortise locks. | Older homes or commercial buildings with mortise locksets. |
| Adjustable Strike Plate | Offers adjustability for misaligned doors and frames. | Doors with slightly warped frames or that don't close perfectly. |
Choosing the Right Strike Plate
Selecting the appropriate strike plate is important for security and functionality. Consider these factors:
- Lock Type: Match the strike plate to the type of lock you are using (e.g., latch bolt or deadbolt).
- Door Frame Thickness: Ensure the strike plate is the correct size for your door frame.
- Material: Choose a durable material such as steel or brass for enhanced security.
- Finish: Select a finish that complements your door hardware.
- Security Needs: For exterior doors or areas requiring higher security, opt for a reinforced deadbolt strike plate.

Door Strike Plate FAQs
Here are some frequently asked questions about door strike plates to help you better understand their purpose and function.
Why is a strike plate needed on a door?
A strike plate reinforces the door frame where the door latch or bolt engages. Without it, the latch would simply dig into the softer wood of the frame, weakening it over time. A properly installed strike plate significantly increases the door's security and durability. It also ensures smooth operation of the latch.
What is a strike plate on a door, exactly?
A strike plate is a metal plate mortised into the door frame that receives the latch bolt or deadbolt when the door is closed. It provides a secure point of contact and helps prevent the door from being easily forced open. It also protects the door frame from damage.
What are the different types of strike plates?
There are several types, including standard strike plates, extended lip strike plates (offering extra frame protection), and deadbolt strike plates (designed for larger deadbolts). Some also include security features like reinforced metal or multiple screws.
How do I know if my strike plate is properly installed?
A properly installed strike plate sits flush with the door frame, allowing the latch or bolt to engage smoothly and completely. If the door requires excessive force to close, or the latch feels loose, the strike plate may be misaligned or installed incorrectly. Check that the screws are tightly fastened and that the plate is securely mortised into the frame.
