Balancing a therapeutic and homely environment with window safety poses unique challenges in Mental Health units.  Open windows provide an opportunity for escape, to throw objects or pass contraband.  Yet permanently closed windows limit fresh air, which is essential to aid recovery.

That's why we designed our anti-ligature window restrictors to be robust and safe, yet also offer flexibility and maximise air flow. 

Our made-to-measure three-part restrictors are designed to meet speciifc requirements in higher risk environments, while our two-part restrictors are suitable for low-risk environments.

Hold-open magnets

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

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.

  • Trial kits for on-site testing
  • Quick and simple to install




Hold-closed magnets

During refurb, existing windows often need updating – for example, removing casement stays.  Hold-closed magnets offer an innovative alternative that keeps windows securely shut.

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

  • For windows without espagnolette locks
  • Ideal for refurbishing old windows
  • Ideal substitute if no locking mechanism is available
