The door handle bracket and latch assembly of the present invention includes a bracket subassembly and a latch. The latch has a spring mounted rotor and a spring mounted catch which function to maintain a door in a latched or unlatched condition. The bracket subassembly includes a mounting plate, a pivotally mounted trip lever, and a rotational release cam receiving the drive shaft of the door handle. Upon rotation of the door handle in either a clockwise or counterclockwise direction, the release cam pivots the trip lever, which in turn pivots the catch out of retentive engagement with the rotor, such that the rotor rotates to the unlatched position to allow the door to move from the latched closed position to an unlatched open position. The assembly has a simple design with a low profile and versatile mounting options.
