Abstract: A heavy duty door handle and lock apparatus has a housing, a first handle on a first side of the housing, and a second handle on the second side of the housing. The handles are movable independently to retract a latch that extends from the housing. A lock cylinder is provided on one side of the housing. When the lock cylinder is in an unlocked position, both of the handles may be moved to retract the latch. When the lock cylinder is in a locked position, movement of one of the handles retracts the latch but movement of the other of the handles does not retract the latch.
