1. An egress point, comprising:
a door frame defining an opening allowing egress;
a door connected to the door frame, the door rotatable between a closed position blocking pedestrian egress through the door frame and an open position allowing pedestrian egress through the door frame; and
an exit device, comprising:
at least one latch having a latched position operable to secure the door in the closed position, the latch having an unlatched position allowing the door to be moved from the closed position toward the open position;
a push bar extending laterally on the door, the push bar moveable toward the door to actuate the latch from the latched position to the unlatched position;
a vertical rod connecting the push bar to the latch, a push on the push bar moving the push bar toward the door and thereby rotating the vertical rod through a rotation to actuate the latch from the latched position to the unlatched position; and
an intermediate transmission assembly, comprising:
an input undergoing a translation in response to the push bar receiving the push to move the push bar toward the door; and
a rotatable output undergoing a rotation about a rotational axis in response to the translation of the input, the rotational axis of the rotatable output extending in a direction from the output towards the at least one latch.
