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 healthcare institutions. The shape and construction of the 5SS55 & 5SS19 Series locksets are designed to restrict the attachment of lines, laces and other items 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 eliminated.
