Anti-Ligature Double Swing Aluminium Hinge Solution

Combines Intastop’s Double Swing Hinge, Removable Doorstop and Concealed Door Closer and is ideal for doors that need to swing 180°. A unique patented anti-barricade package that offers quick opening in emergency situations. It provides an ideal solution for busy corridor doors which are exposed to impact damage and toilet/ shower room doors where there is a risk of barricade or patients collapsing in the room. It is designed for 44 mm doors, for high impact areas and heavy doors up to 160 kg; for doors greater than 44 mm an additional packer piece is available, which allows the hinge to fully open 90º in both directions.

Concealed closer:

Mental health has special dispensation which states a closer can be exempt on fire doors to bedrooms in mental health accommodation (HTm05-2). Intastop are now able to give end users the choice. The patented Double Swing Hinge works with a concealed floor or frame mounted closer meaning there is the option which combines both reduced ligature and the possibility for a closer for bedrooms in mental health applications. This anti-ligature closer has a closing force size 3–6 and is suitable for leaf widths up to 1100 mm. The closing speed and latching action is adjustable and comes complete with a safety valve to prevent deliberate overloading. It has a closing range from approximately 180° and is CE approved in accordance with EN 1154 and Certifire approved in accordance with EN 1634-1.

Improved acoustic performance:

For improved acoustic performance a Full Mortice Automatic Door Bottom is available to suit the Double Swing Hinge.
