There are three main functions available on most windows: closing, opening and adjusting the window’s open position. Every single one is made possible by one mechanism known as a window winder. Also known as window regulators in the automotive world, they enable smooth and safe operation without being a pain to use.
This is especially true with a lockable window winder, which adds a higher level of security and makes for a more reliable component altogether. The same window chain winders can be used on different types of windows, and it’s quite easy to incorporate them into existing windows, even with older designs.
How a Chain Window Winder is Installed and Used

Attachment
As long as your window has a chain mechanism, the rest is rather easy to put in place and use. In order to do the latter, you first need to secure the chain winding mechanism to the chain, which often comes with a tool that helps you with it. A lockable window winder is properly installed once it fits snugly and has a secure connection with the window.
Handle
After the mechanism is attached, you can turn its handle clockwise or anti-clockwise, depending on whether you want to open or close the window. The number of turns determines how open the window will be and stay that way, too.
Adjustment
Once the smooth operation of the winder is on your side, you can adjust the opening of the window so that you don’t have to always turn the handle to open it to that position. Doing so requires minimal effort; all you need to do is open it at the desired position and then lock the window at said position using the key that comes with the winder.
Types of Chain Window Winders
Single
The simplest window chain winder you can get is a single-chain mechanism, which has a smaller footprint. Therefore, a single-chain winder is suitable for lighter awning windows measuring less than 1.2m². This type of window winder is ideal for sunrooms and as a retrofit solution since it’s easy to install, requires very little maintenance and is the more cost-effective option than its larger counterpart.
Twin
A twin chain window winder is larger because it houses two chains instead of one, which helps with force distribution. This is also why twin chain winders are used on windows larger than 1.2m², which are more common in schools, hospitals and storage facilities. These types of winders are also able to reduce hinge wear and sash distortion much better than single-chain winders.
Benefits of Chain Window Winders
Emergencies
One of the most underestimated advantages of a window chain winder is the level of protection it offers in an emergency. Be it during a fire or a power outage, a chain window winder can help with smoke ventilation without issues and can be used reliably when there is no power, which can also occur during a fire.
Corrosion
Because the internal components of the mechanism, a chain winder, are made of extruded aluminium or stainless steel, which are both corrosion-resistant materials. Even if you live near the coast, you can rest assured that the piece of hardware you install on your window will stay operational for years to come.
Standards
Window chain winders undergo various tests to ensure they meet Australian standards, such as AS4145.3 window lock certification, ICP005 force tests and AS2331.1.1 salt spray certification to make sure they are reliable and long-lasting.
Versatility
No matter the size and type of window you have, as long as it can be opened, you can install a window chain winder. You can make any window more practical and safer while retaining its visual presence and usability.
Aesthetics
When it comes to your window’s appeal, you can keep its aesthetics the same with a window winder, no matter where you install it. The minimalist appearance of the winder keeps it from distracting from the window’s design; in fact, it can even enhance its looks in some cases.
Ease of Use
It doesn’t get simpler than using a window winder, especially since it is much safer and more reliable than using a window without one. The simplicity of the mechanism allows even a child to use it, and its limited opening of 120mm helps prevent accidental falls. This means it meets the Australian “No Child Can Fall” standard.
Conclusion
Adding an upgrade to an already simple and effective solution can seem unnecessary, but when it comes to improving its features, it can be valuable. This is exactly what a window winder is to those who use it, and it can be just as useful in your household or office, as it’s easy to implement and doesn’t compromise usability.
