Ligature Resistant Door Hardware

How Can we Help?

    Ligature Resistant Hardware

    In December of 2017, the Center for Medicare & Medicade Services released a memo stressing for a bigger focus on assessing ligature risk in healthcare environments. Currently, 75% of all psychiatric ward suicides are via asphyxiation through hanging or environment assisted strangulation.

    While not all incidents are wholly preventable, the CMS understand that ligature resistant hardware is the best solution to protect safety of patients in these cases.

    Marks USA Custom Lock Division has developed ANSI Grade 1 Institutional Life Safety Locksets to address Managed Liability, Accident Prevention, Life Safety and Security in Behavioral Health Care Institutions. The shape and construction of the 5SS55 & 5SS19 Series locksets are designed to restrict the attachment of lines, laces, etc. to door knobs and levers. In addition, with the knobs/levers recessed into the rosettes, the chance of capturing a line between the knob/lever and rosette is substantially reduced. Their Lifesaver Series of anti-ligature hardware meets or exceeds key healthcare regulations, such as JCAHO and ADA.
