The keyless cable window restrictor offers a reliable and discreet way to improve both child safety and home security, while still allowing fresh air to circulate. With a 20cm hardened steel cable, it limits the window opening to under 89mm–100mm when installed correctly — small enough to prevent children from fitting through, but wide enough to maintain effective ventilation in any room.

The newly upgraded push-to-lock mechanism allows the cable to be secured with a simple press — no key required. This makes it ideal for situations where quick operation is essential, while still providing peace of mind that the restrictor will hold firmly once engaged. It’s even suitable for fire escape windows when installed in compliance with safety regulations.

One of the standout features of this restrictor is the strength of its locking system. Once the cable is secured in place, it can withstand forces exceeding 100kg — more than double the industry standard of 50kg. This added strength ensures the device can comfortably support the weight of a child and resist significant tampering or force.

Constructed from hardened steel, the cable itself is highly resistant to cutting, making this restrictor a practical solution for ground-floor properties or homes concerned about potential break-ins. It allows residents to leave windows slightly open for airflow, while maintaining a high level of security.

Finished in white, black, or brown, this keyless restrictor blends effortlessly with most window frames, offering both function and style in equal measure.
