To provide a secure and hygienic solution for privacy in high-risk environments, the Anti Ligature 8mm Turn and Release is the professional choice for heavy-duty safety applications. Engineered specifically for use with commercial-grade mortice locks, this hardware eliminates suspension points while ensuring healthcare staff have the emergency access and durability required for mental health wards and correctional facilities.
In specialized clinical and detention environments, standard bathroom hardware can be exploited as a point of suspension. The Anti Ligature 8mm Turn and Release is designed to mitigate this risk through a specialized “sloped” or “elephant-ear” geometry. By utilizing a smooth, tapered profile that angles sharply toward the door leaf, the hardware ensures that any cord, clothing, or material placed over it will immediately slide off under tension.
What sets this unit apart from standard residential privacy sets is the 8mm spindle. Most domestic thumbturns utilize a 5mm spindle, which is insufficient for the high-torque, heavy-duty mortice locks found in commercial and institutional buildings. The Anti Ligature 8mm Turn and Release is built to bridge this gap, providing a robust mechanical connection that can withstand constant use and physical abuse in high-traffic wards.
Why the Anti Ligature 8mm Turn and Release is the Industry Standard
-
Ligature-Resistant Geometry: The fully radiused and chamfered edges of the Ant -Ligature 8mm Turn and Release ensure there are no sharp corners or grip points for ligatures.
-
8mm Spindle Compatibility: Specifically designed to work with heavy-duty commercial privacy locks and high-security mortice bolts, ensuring a seamless fit without the need for spindle sleeves or adapters.
-
Grade 304 Stainless Steel: Forged from premium-grade alloy, Anti Ligature 8mm Turn and Release is naturally resistant to corrosion and the harsh chemical disinfectants required for modern infection control protocols.
-
Tamper-Proof Security Fixings: Every set is supplied with heavy-duty bolt-through fixings (typically Pin-Hex or Torx). This ensures the hardware is clamped through the door, making it virtually impossible to remove or dismantle without specialized tools.
-
Emergency Override: The external “Release” component features a discreet coin-slot or driver notch, allowing staff to gain instant access to a locked room in the event of an emergency.
-
Fire Rated Integrity: Fully tested and certified for use on 30-minute and 60-minute timber fire doors, ensuring that your facility remains compliant with both life-safety and fire-safety regulations.

Achieving a “Zero-Gap” Professional Installation
The safety of an Anti Ligature 8mm Turn and Release is entirely dependent on a “zero-gap” fitment. In high-risk environments, even a 1mm gap can be exploited.
-
Flush Surface Mounting: Ensure the door leaf is perfectly flat. If the door is warped, the rose may “bow,” creating a gap. Installers should sand or level the door surface before final tightening.
-
Spindle Alignment: Because the 8mm spindle is thicker than standard, ensure the mortice lock hub is perfectly aligned with the boreholes. Any misalignment can cause the turn to “bind” or feel stiff, which can lead to mechanical failure over time.
-
Anti-Pick Sealant: In maximum-security settings, it is best practice to apply a thin bead of anti-pick, security-grade mastic around the entire perimeter of both the Turn and the Release. This prevents the insertion of thin wires or threads behind the hardware.
-
Security Bolt Tension: Use a torque-limited driver to ensure the bolt-through fixings are tight enough to compress the plate against the door without stripping the precision-machined threads.
