Certified Anti-Ligature Covers & Ligature-Resistant Hardware
Oystashell® anti-ligature covers are engineered to protect wireless access points, CCTV systems and exposed infrastructure in healthcare, custodial, educational and public-facing environments where safety, durability and operational reliability all matter equally.
Each enclosure features smooth, four-sided, sloping geometry to minimise loop hazards, exposed anchor points and accessible pry gaps often associated with standard housing. Manufactured from 3mm high-impact riot-shield-grade polycarbonate with riot-shield-grade durability, the covers resist cracking, shattering, tampering and repeated impacts in demanding spaces.
Flush-mounted 6-point hex star security fixings help prevent unauthorised access while maintaining a clean, seamless installation against walls and ceilings. The RF-transparent material preserves wireless signal performance with less than 1dB of signal loss, allowing critical infrastructure to remain fully operational.
Available in both clear and opal finishes, the Oystashell® product range also supports calmer, less institutional environments by concealing internal hardware and softening the visibility of status lights.

How Oystashell® Anti Ligature Covers Improve Safety
Standard cages and generic enclosures can unintentionally create accessible gaps, attachment points or exposed edges that increase environmental risk.
Oystashell® anti-ligature systems are designed to reduce those vulnerabilities while protecting critical hardware from impact, interference and tampering.
The sloped profile removes leverage points and limits opportunities for attachment, while the durable polycarbonate shell withstands deliberate damage and heavy daily use. Flush security fixings keep the enclosure tightly aligned to the mounting surface without restricting authorised maintenance access.
Alongside physical protection, the RF-transparent construction allows wireless signals to pass through with minimal interference, helping networks and surveillance systems remain reliable in busy facilities. The long-lasting construction also helps reduce the need for repeated hardware replacements, room downtime and ongoing maintenance costs.

Why Choose Oystashell® Anti-Ligature Enclosures?
Secure Infrastructure with Flush Security Fixings
A protective enclosure is only as secure as its fixing system. Exposed screws or raised mounting points can quickly become vulnerable areas within high-risk environments.
Oystashell® anti-ligature enclosures use a flush-fitting 8-point hex-star security screw system designed to reduce leverage points and resist unauthorised tampering. Once installed, the enclosure remains tightly aligned against the mounting surface while still allowing authorised maintenance teams to access internal hardware when required.
Supporting Calmer Environments Through Non-Institutional Design
Traditional metal cages can appear harsh and overly institutional within healthcare and behavioural settings. Oystashell® anti-ligature cover systems use a softer architectural approach that integrates more naturally into modern interiors.
The smooth profile, clean ceiling integration and optional opal finish help conceal internal hardware and soften the appearance of visible status lights without compromising protection. This creates a more discreet infrastructure solution suited to environments focused on safety, well-being and long-term durability.
Suitable for High-Risk Healthcare and Custodial Sectors
Oystashell® anti-ligature systems are widely specified across environments where safer infrastructure, protected wireless connectivity and secure CCTV deployment are required.
Applications include:
- NHS trusts and mental health facilities
- Police and correctional environments
- Schools, gymnasiums, leisure centres
- Specialist educational settings
- Public buildings and restaurants
- Transport hubs
- Industrial and high-traffic facilities
The combination of anti-ligature geometry, tamper resistance and durable polycarbonate construction makes the range suitable for spaces where both safety and operational resilience remain essential.
Reduce Long-Term Maintenance Costs
Repeated hardware damage can create unnecessary maintenance expenses, replacement cycles and room downtime across busy facilities. Lower-grade plastic housing often cracks or fails under repeated impact, particularly within high-traffic environments.
Oystashell® ligature-resistant hardware is manufactured from 3mm high-impact polycarbonate engineered for long-term durability. The material is approximately 250 times stronger than glass while remaining lightweight and RF transparent for wireless signal performance.
This helps facilities reduce replacement cycles and maintain stable operational costs in the long run across wireless and surveillance infrastructure.
Mitigate Facility Risk With Ligature-Resistant Hardware
Within healthcare and custodial settings, exposed fixtures and poorly designed housing can introduce avoidable liabilities. Conventional metal cages may physically protect hardware, yet still create accessible fixing points or harsh institutional aesthetics that run counter to safer room design principles.
Oystashell® ligature-resistant hardware is developed specifically for environments where duty of care, compliance and operational continuity must work together. The anti-ligature geometry helps reduce opportunities for attachment while maintaining full protection for wireless infrastructure and CCTV systems.

FAQs
Are Oystashell® covers suitable for NHS mental health environments?
Selected Oystashell® anti-ligature covers are engineered using ligature-resistant design principles to mitigate risks identified in clinical safety audits.
They feature smooth, sloping geometry and fewer attachment points, supporting safer infrastructure and reducing attachment risks, as required in mental health facilities, behavioural healthcare settings and other high-dependency spaces.
Final suitability should always be assessed against individual project requirements and local compliance procedures. You may also talk with our professionals to find out and ascertain.
How does anti-ligature design reduce prying and attachment risks?
The enclosure uses smooth, four-sided, sloping geometry with minimal exposed edges, accessible gaps or leverage points. When combined with flush-mounted security fixings, this helps reduce opportunities for attachment, tampering or forced access.
Can technicians service internal hardware without fully removing the enclosure?
Yes, the security-fixing system allows authorised maintenance personnel to access internal wireless hardware for servicing, upgrades and inspection while maintaining secure day-to-day installations.
Are Oystashell® enclosures fire-rated for public buildings?
Oystashell® enclosures are manufactured from polycarbonate with a B-s1,d0 fire rating under EN 13501-1:2018, meeting stringent fire performance requirements for many public-sector and healthcare environments. Project-specific fire compliance requirements should always be reviewed against local building regulations and installation standards.
Warning: The anti-ligature design features of this product are not intended to replace or substitute the need for necessary supervision of those who may be at risk, or for other necessary protective measures to be taken in the specific circumstances of usage.
Oystashell does not claim any product to be totally ligature-free, or make claim that they cannot be damaged with regard to anti-vandal features. It is therefore the customer’s responsibility to ensure the suitability of the product for the environment in which they are to be fitted.
