The concertina design enables the security grille to retract to 15% of the overall width, allowing the grille to disappear neatly behind curtains.
With various security levels of retractable grilles available, there is the right security grille for any application, from your home and office, right the way through to high risk commercial and public sector applications.
These higher security level grilles have all been independently tested by the Loss Prevention Certification Board, achieving a security rating up to LPS1175 security level 3.
