Step-by-Step Instructions for Installing a Metal Screen Door

Step 1: Gather the Necessary Tools and Materials

Select a metal security door that comes with attached hinges for easier installation. Make sure to choose the door based on the measurements of the opening it will cover. When purchasing the door, ensure that all the necessary mounting hardware is included. Refer to the manufacturer’s instructions to confirm that you have all the required hardware and accessories for your project. Since models may differ, follow the manufacturer’s user guide for specific installation instructions and diagrams. Lay out all the installation accessories and tools for easy access and reference.

Step 2: Measure the Opening and Cut the Z Bar

Use a tape measure to determine the height of the door opening. Measure from the top inner frame (header) to the lower inner frame (threshold) of the door. The Z bar, which is included with the door, will attach to the metal screen door. Ensure to wear safety glasses and gloves during the installation process. Use a hacksaw to cut the Z bar to fit within the door opening. To do this, cut the Z bar 3/16 inch smaller than the width of the door frame.

Step 3: Check for Proper Fit

Place the metal security screen door inside the door opening and check if it fits properly. Make any necessary adjustments. It is helpful to have a partner hold the door in place while you begin drilling.

Step 4: Hang the Metal Screen Door

Use a power drill to secure the door to the brick molding. This can be done by using the screws provided in the manufacturer’s installation hardware. Drill the screws through the holes in the hinge, then drive them through the Z bar and into the molding. Open and close the door to ensure that it is evenly hung.

Step 5: Secure the Header

Position the header piece above the metal security screen door. Locate the pre-cut holes in the header to determine the placement of the screws. Use a screwdriver that matches the size of the supplied screws to screw the header in place.

Step 6: Install the Expander

Open the door and slide the expander piece along the bottom of the security screen door. The expander is a strip that acts as a barrier to prevent debris from accumulating beneath the door. Use an electric drill to screw the expander into place. Open and close the door again to ensure that there is enough clearance once the expander is installed correctly. Once the expander is securely in place, the installation is complete.
