Steps To Install Security Door

Follow these six steps to safely install your new security door.

Step 1. Required Tools And Materials

• Choose a metal security door with attached hinges for ease of installation.
• Your selection needs to be based on measurements of the door it will soon cover.
• Include all necessary equipment for mounting purposes with your purchase.
• Refer to the manufacturer’s instructions to see if you have all the necessary equipment.
• Follow manufacturer’s instructions for the installation process.

Step 2. Measure Opening And Cut Z Bar

• Use a tape measurer to measure the height of the door opening.
• Measure all the way from the lower inner frame to the top inner frame.
• The “Z bar” is the piece that attaches to the metal screen door.
• Wear gloves and safety glasses while performing this step.
• Using a hacksaw, cut the Z bar to fit within the door opening.
• Cut the Z bar 3/16-inch smaller than the width of the door frame.

Step 3. Proper Fitting

• Now place the metal security door within the door opening.
• Make sure it fits properly.
• If needed, have a partner hold the door in place as you are drilling.

Step 4. Hang Metal Screen Door

• Using a power drill, secure the door to the brick molding next.
• Use the screws included in the manufacturer’s installation hardware to perform this task.
• Next, drill the screws through the holes that are found in the hinges.
• Now drive the screws through the Z bar, into the molding.
• Make sure it is hung evenly by attempting to open and close the door.

Step 5. Secure Header

• Place the header piece atop the security screen door.
• Find the precut holes in the header.
• The holes will determine where you’ll need to put the screws.
• Match the size of the screws with the proper screwdriver blade size.
• Screw the header into place with the screwdriver.

Step 6. Install Expander

• Slip the expander piece along the bottom of the door after opening the door.
• This is a strip that acts as a barrier, which keeps debris from collecting beneath the door.
• Screw the expander into place with an electric drill.
• Check to see if there is enough clearance by opening and closing the door afterward.
