ANSI Grade 1 Extra Heavy Duty
When a safe environment is needed
A lock is thought to be safe when it prevents forced intrusion. But is that the only risk we may encounter?
In recent years, suicide rates have increased alarmingly, among which ligature strangulation is one of the most common cases of self-inflicted injury. This typically occurs in buildings such as detention centers, hospitals, mental health centers, where mere constant monitoring is insufficient to prevent disasters to happen.
Klacci’s Anti-ligature Solutions provide the perfect hardware to prevent ligature attachment and self-harm, thus ensuring a risk-free environment.
