Mul-T-Lock’s  Hercular® Grade 1 Anti-Ligature Deadbolt (also available with latch locking) meets the unique locking needs found in institutions such as health care facilities where its lack of angles greatly decreases risk of injury or self-harm.

Anti-Ligature fixtures in hospitals also serve as an easier to operate hardware alternative for individuals with injuries or a weakened grip as they are easy to operate and include a smooth design with less opportunity for accidental injury (such as snagging a bandage).

Offered in a deadbolt function which allows for unlocking from the inside at all times while preventing locking from the inside and a convenient latch locking variation as well.
