INOX introduced the PD3000 Narrow Profile Mortise Lock for Sliding Doors, a commercial-grade narrow stile lock with a self-latching function that easily retrofits into existing narrow profiles. The new lock is a self-latching deadlock/deadlatch for wood sliding doors in health care facilities, such as ICU doors. The hook bolt remains retracted until the door is closed, and the built-in actuator contacts the strike, which automatically self-latches the bolt into the strike.
