What Does the Metal Piece on Door Frames Do?

The metal piece on door frames, commonly known as a strike plate, serves several important functions. It provides a surface for the door latch to strike against, reinforces the door frame, reduces wear and tear on the door frame, and secures the door in the closed position.

Provides a Surface for the Door Latch to Strike Against

One of the main purposes of the metal piece on door frames is to provide a surface for the door latch to strike against when the door is closed. This ensures that the door remains securely closed and prevents it from swinging open unintentionally.

Without a strike plate, the latch would have nothing to latch onto, compromising the security and functionality of the door.

Reinforces the Door Frame

The metal strike plate reinforces the door frame by providing additional strength and stability. When the door is closed, the force exerted on the strike plate is distributed evenly across the frame, reducing the risk of damage or warping.

This reinforcement helps to extend the lifespan of the door frame, making it more durable and resistant to wear and tear.

Reduces Wear and Tear on the Door Frame

The metal strike plate acts as a buffer between the door latch and the door frame, reducing the direct impact and friction that would otherwise occur. This helps to minimize wear and tear on the door frame over time.

Additionally, the strike plate absorbs some of the force when the door is closed, preventing the latch from damaging the wood or other material of the frame.

Secures the Door in the Closed Position

Another important function of the metal piece on door frames is to secure the door in the closed position. The strike plate provides a fixed point for the door latch to engage, ensuring that the door remains tightly shut.

This is crucial for maintaining privacy, keeping out drafts, and enhancing the overall security of the space.

Types of Door Striker Plates

Standard/Flat Plate

The standard or flat plate is the most common type of door striker plate that you will find on door frames. It is a simple, rectangular metal piece that is attached to the door frame using screws. This type of striker plate is designed to provide a smooth surface for the door latch to slide into when the door is closed, ensuring a secure and tight closure.

The flat plate is typically made of durable materials such as steel or brass to withstand regular use and prevent wear and tear.

Box Strike Plate

The box strike plate, also known as a full lip strike plate, is a variation of the standard plate that offers enhanced security. It has a deeper recess and a lip that extends further into the door jamb, making it more resistant to forced entry attempts.

The box strike plate is commonly used in homes and businesses where extra security is desired.

T-Strike Plate

The T-strike plate, as the name suggests, has a T-shaped design. It is often used for interior doors and offers improved strength and stability. The vertical part of the T fits into a recess in the door frame, while the horizontal part sits flush against the edge of the door.

This type of strike plate helps to distribute the force of closing or opening the door more evenly, reducing the risk of damage to the door frame over time.

Angled Strike Plate

The angled strike plate, also known as an offset strike plate, is specifically designed for doors that do not align perfectly with the door frame. It has an angled surface that allows the latch to catch and secure the door even if it is not perfectly aligned.

This type of strike plate is commonly used in older buildings or in cases where the door frame has shifted over time.

Aluminum Strike Plate

The aluminum strike plate is a lightweight and corrosion-resistant option that is often used in exterior doors. It provides a strong and durable surface for the door latch to engage with, ensuring a secure closure.

Aluminum strike plates are commonly used in areas with high humidity or coastal regions where moisture can cause rust or degradation of other materials.

Long Strike Plate

The long strike plate, also referred to as an extended strike plate, is designed to cover a larger area of the door frame. It provides additional reinforcement and security by distributing the force of a potential break-in attempt over a wider area.

This type of strike plate is commonly used in commercial buildings or high-security applications where added protection is required.

How to Install a New Door Striker Plate

Step 1: Remove the Existing Striker Plate

The first step in installing a new door striker plate is to remove the existing one. This can typically be done by unscrewing the screws holding it in place. Use a screwdriver to carefully remove the screws, making sure not to strip them in the process.

Once the screws are removed, gently pull the striker plate away from the door frame.

Step 2: Chisel Out Space for the New Plate

After removing the old striker plate, you will need to chisel out space for the new plate. Use a chisel and hammer to carefully remove any excess wood or paint from the area where the new plate will be installed. Take your time and be precise to ensure a proper fit for the new striker plate.

Step 3: Insert the New Plate

Once you have chiseled out the necessary space, it’s time to insert the new striker plate. Position the plate in the designated area and make sure it aligns with the latch on the door. Use your fingers to hold the plate in place while you move on to the next step.

Step 4: Secure the New Plate with Screws

Now that the new striker plate is in position, it’s time to secure it with screws. Use a screwdriver to carefully insert the screws into the pre-drilled holes on the plate. Tighten the screws until they are snug, but be careful not to over-tighten and strip the holes.

Step 5: Test the Door Latch

After securing the new striker plate, it’s important to test the door latch to ensure it is functioning properly. Close the door and attempt to latch it shut. If the latch easily catches and holds the door in place, then you have successfully installed the new striker plate.

If there are any issues with the latch, double-check your installation and make any necessary adjustments.

Installing a new door striker plate is a straightforward process that can greatly improve the functionality and security of your door. By following these steps, you can easily replace the old plate with a new one and enjoy a properly functioning door latch.

How to Replace a Damaged or Worn-Out Door Striker Plate

Step 1: Unscrew and Remove the Old Plate

If you have noticed that your door is not closing properly or the latch is not aligning with the strike plate, it may be time to replace the door striker plate. The striker plate is the metal piece on the door frame that the door latch engages with when the door is closed.

Over time, the striker plate can become damaged or worn-out, causing issues with the door’s functionality. To replace it, start by unscrewing and removing the old plate using a screwdriver.

Step 2: Clean Out the Mortise

Once the old plate has been removed, it’s important to clean out the mortise, which is the recessed area on the door frame where the striker plate sits. Use a chisel or a flathead screwdriver to remove any debris or old paint that may be blocking the space.

This will ensure that the new plate fits properly and functions correctly.

Step 3: Position and Mark the New Plate

Next, position the new striker plate over the cleaned mortise area and align it with the door latch. Use a pencil or marker to mark the screw holes on the frame. This will guide you when it’s time to secure the new plate in place.
