Anti-ligature window restrictors

Ensuring window safety with our specialized anti-ligature restrictors, designed to prevent accidental falls and unauthorized entry while maintaining ventilation.

Window restrictors: balancing a therapeutic environment with window safety


Fresh air and views of the outdoors are essential to recovery but wide opened windows pose unique safety concerns to Mental Health patients. We designed our window safety restrictors to address specific Mental Health requirements, which is why they are robust and safe yet offer flexibility and maximised airflow. Our made-to-measure three-part restrictors are designed to meet specific requirements in higher-risk environments, while our two-part restrictors are suitable for low-risk situations.


Here are some of the benefits of our Anti-Ligature Window Restrictors:


  • Robust, Anti-tamper, Corrosion-resistant fittings
  • Keyless operation
  • Finished in any RAL colour
  • Top or side-hung vents
  • Anti-ligature (DHF TS001)
  • Suitable for PVCu, timber and aluminium frames
  • Available in a wide range of sizes or made-to-measure window restraintGET IN TOUCH CTA

Retrofit Window Restrictors

Windows in existing buildings are often identified as a risk. So our retrofit restrictors deliver appropriate window security levels without replacing the window itself – reducing costs and minimising patient disruption.


Within new builds, designing out risks with sliding windows is the ideal scenario – but it isn’t always within budget. We work with manufacturers and contractors to provide safe and cost-effective retrofit window restrictors.

Hold-open Magnets

If windows need to be held open, our magnetic solution avoids the ligature risks of window stays, protecting patients from self-harm.

Existing windows often need to be updated during refurbishment – for example, removing casement stays. Hold-closed magnets offer a functional alternative that keeps windows firmly shut.

Hold-closed Magnets

Small but powerful, our magnets require no power, making installation quick and inexpensive with minimal disruption. And with no moving parts, there’s nothing to break and no maintenance problems.

Hold-closed magnets are always made to measure due to the differing space between the vent and inner frame. We’re always happy to offer specification assistance.
