Window winders are a quick and easy way to open and close awning windows. They're also simple to install and we'll show you how. You'll learn how to measure up and attach the winder to the window, and pick up a few handy tips to get the job done right.


1Measure 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.

2Drill 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.

3Fix 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.

4Drill 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.

5Fit 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.
