How to install casement window stays

Overview

The stay arm is a great way to tightly lock a casement window in place. We'll teach you how to install the arm onto the window properly. You will also learn how to install the arm fixers so the window closes tightly on the frame.

Steps

1Mount the casement window stay onto the window frame

Place your stay on the window frame, slightly off-centre, away from the hinged side of the window. Then use a pencil to mark where the first screw hole should go. Now remove the stay, open your window, drill a pilot hole and screw the stay onto the frame. Now the stay is in place, screw the pilot hole for the second screw and drive it into place.

2Install the casement window stay fixers to the bottom of the window frame

Close the window and position the first fixer in the first hole of the stay arm. Mark where the fixer sits on the frame, then remove the arm, drill pilot holes and screw the fixer into place. Now put the second fixer in the final hole of the arm, push the arm tight against the window and mark where it sits. Once again, remove the arm and drill pilot holes. Then screw the fixer into place, replace the casement stay arm and the job is done.

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. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
