MEDIATOR® lock, tubular frame version. The MEDIATOR® lock in the tubular frame version is available in various backset sizes and with extensive accessories. Self-locking: bolt and latch are locked, thus increasing security. Mechanical sequence control between cross latch and control latch. Integrated panic function via the inside handle. Changeover function for unlocking with a key from the outside. The MEDIATOR® locks have a continuous handle follower and therefore require an interchangeable fitting (inside handle or panic handle bar, outside knob or handle bar).
