SS55 Series Institutional Life Safety Locksets

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 SS55 Series Locksets are designed to restrict the attachment of lines, laces, etc. to door knobs. In addition, with the knobs recessed into the rosettes, the chance of capturing a line between the knob and rosette is substantially eliminated. These locksets have specially designed finger indented safety knobs with recessed grip and ergonomically designed integral grooved turn knobs for elderly and handicapped access (Patent #D587556).
Common pin tumbler cylinders may be compromised by picking, drilling or key bumping. For applications where a greater security level is required, we suggest using pick/drill resistant cylinders with multiple pin planes such as those with side-bars.
Marks USA HI-SECURITY™ Cylinders are constructed with sidebars and are drill, pick and bump resistant.
