This D.I.Y. Advice is part of a series How To Install an Awning Window

Step by Step Instructions

1 Measure the centre of the window
2 Drill in pilot holes for the chain
3 Fix the winder chain to the window sash
4 Drill in the pilot holes for the window winder
5 Fit the winder to the windowsill
  • Step 1. Measure the centre of the window

    First, make sure the window is closed. Take your ruler and measure the centre of the window on the bottom of the window sash.  Once you’ve marked it with your pencil, place the window winder into position with the chain attachment centred over that mark. 

  • Step 2. Drill in pilot holes for the chain

    Take your pencil and mark out the screw points through the holes of the chain attachment. Remove the winder and drill some pilot holes into those marks with your power drill. It’s a good idea to open the window to protect the windowsill. 

  • Step 3. Fix the winder chain to the window sash

    Now, take the window winder and wind the chain out a little bit to make more room for your screwdriver. Position the end of the chain over the pilot holes and drive the screws tightly into the window sash with the screwdriver.

  • Step 4. Drill in the pilot holes for the window winder

    Hold the winder into position on the windowsill. Pull the window closed as tightly as you can. Allow an even gap between the winder and the window sash, with just a little bit of spread, so that the window will wind in nice and tight. Mark the screw holes by pressing a nail into the timber. Remove the winder and drill in some pilot holes. 

  • Step 5. Fit the winder to the windowsill

    Place the winder into position again, over the pilot holes. Use your screwdriver and screws to screw the winder tightly onto the sill. Once you’re done, it’s a good idea to test the winder and make sure that it’s opening and closing properly.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
