ABSTRACT:
An emergency exit device mounted on the inner face of an outwardly opening door includes top and bottom latches mounted near the beveled or free side edge of the door and connected to an operating unit by vertically extending rods. The operating unit is at all times operable to release the latches in response to pressure applied in a door opening direction to a push bar which extends across the inner face. The latches are released from the outer side of the door by a rotary operator operably connected to the operating unit and having a conventional backset. The vertical axis of the rods is horizontally offset from the axis of the rotary operator in the direction of the free side edge of the door.
