Whitco CYL4® Push to Lock Chainwinder – Secure Ventilation Made Simple
At Aus Lock and Safe Co, we know that awning windows are a favorite for Melbourne homes, but they can be a security headache. The Whitco CYL4® Push to Lock Chainwinder is the ultimate solution. It replaces your standard, flimsy winder with a high-security, key-lockable unit that lets you enjoy the breeze without leaving your home vulnerable.
The "magic" of this winder is the CYL4® technology. It allows you to use your standard front door key to lock and unlock your windows. No more searching for that one tiny window key buried in a kitchen drawer—one key does it all.

Features & Benefits
- CYL4® One-Key Security: Can be keyed alike to your front door (C4 profile), giving you the ultimate convenience of a single key for your entire home.
- Push-to-Lock Action: Simply push the button to secure the window. It’s fast, intuitive, and ensures your windows are deadlocked before you leave the house.
- Wound Closed While Locked: Unlike older models, you can wind the window fully shut even when the lock is engaged, meaning you don't have to unlock it just to batten down the hatches during a storm.
- Through-Flyscreen Operation: Designed to work perfectly with flyscreens, allowing you to open and close your windows without letting in the Melbourne summer bugs.
- Foldable Knob: The clever handle knob folds away when not in use, preventing it from catching on blinds or curtains and giving your windowsill a cleaner look.
- Corrosion Resistant: Built with a zinc diecast body and passivated steel components to withstand the elements. For bayside homes, a stainless steel chain version is also available.
