Mul-T-Lock’s Anti-Ligature Hercular® Deadbolt meets the unique locking needs found in institutions such as hospitals and health care facilities where its rounded shapes and lack of angles greatly decrease an occupant’s risk of injury or self harm by incidents such as hanging, pulling off of lock or making contact with edges.
Anti-ligature fixtures in hospitals also serve as an easier-to-operate hardware alternative for individuals with hand/wrist injuries or a weakened grip as they are generally easier to operate than a more complex lock or handle and as their smooth design lends less opportunity for accidental injury (such as snagging a bandage).
The anti-ligature Hercular® deadbolt is offered in a function that allows for unlocking from the inside by use of the thumb turn at all times, while preventing locking from the inside. This feature ensures that quick and easy unlocking of the door from the inside is always accessible to the occupant, while attempts to lock the bolt from the inside using the thumb turn will not succeed, resulting instead in the thumb turn freely spinning without engaging the bolt. From the outside however, both locking and unlocking via a key is always possible.
