  • Step 1. Measure the size of your door

    Measure the height and width of your door jamb/doorway frame before you choose a door. Even though most doorways are a standard size, they will all vary slightly.  Also, work out whether it’s a right or left opening door. You can also get your door made to measure through Special Orders at your local Bunnings.
  • Step 2. Attach the lock and handles

    Follow the instructions that came with your door to attach the locks and handles. Our locking mechanism is attached with two screws. We then slid the spindle into the handles, inserted it through the locking mechanism and attached it with the screws. We then inserted the internal lock.
  • Step 3. Measure and mark for the hinges

    You’ll need someone to help you with this step. Place the door in the doorway. Use wedges to keep it in the right place. Make sure there is a 3mm gap at the top of the screen door, so it doesn’t catch when it’s being opened and closed. Then measure and mark where the hinges should go on the door jamb. Be sure the hinges are fully open before marking with the pencil.
  • Step 4. Make the door jamb square

    Because our house is a little older, the doorframe isn’t square. So, we put the door back in place and traced around the hinges. We then used a hammer and chisel to check out the timber so that the hinges sit flush. Repeat this for the other hinges.
  • Step 5. Pre-drill and attach the hinges

    Pre-drill the holes for the hinges with the 2mm bit. Then screw (30mm) in the top hinge with the 30m screws. Once it’s correctly in place, repeat the process for the bottom and middle hinges. It’s important to do them in this order.
  • Step 6. Mark for the striker

    Close the door and mark where the centre of the striker is. Transfer this around onto the door jamb.
  • Step 7. Drill holes for the striker

    Use the spade bit to drill holes for the striker and latch. The hole needs to be slightly larger than the striker. Check the striker fits in the hold by closing the door.
  • Step 8. Attach the striker

    Pre-drill the pilot holes with the 2mm bit for the screws. Fit the striker plate. Check that the lock and handles work correctly.
  • Step 9. Peace of mind

    And there you have it, a great looking security door that will give you and your family peace of mind in your own home.
