A handle mechanism includes a gear drive having an interior end and an exterior end; an inside handle fixed to the interior end; a button; a finger; a handle drive; an outside handle; and a spring. The button has an interior end and an exterior end, which is positioned within the exterior end of the gear drive. The handle drive is positioned within the exterior end of the gear drive and is rotatable relative thereto. The outside handle and the handle drive rotate together. The outside handle moves between a first position, wherein it is constrained from rotation, and a second position. The finger is fixed to the exterior end of the button, which moves between a first position, wherein the finger causes the gear drive and the handle drive to rotate together, and a second position. The spring biases the button and the outside handle toward their first positions.

A pressure relief latch includes a housing, a bolt, a cam, and a spring assembly. The housing includes a door panel, a first lateral panel, and a second lateral panel. The first lateral panel and the second lateral panel extend outward from the door panel. The bolt includes a bolt body and a roller bearing. The bolt body is pivotably mounted to the first lateral panel and the second lateral panel at a bolt pivot axis. The bolt body is pivotable about the bolt pivot axis between a latched position and an unlatched position. The roller bearing is rotatably mounted to the bolt body. The cam is pivotably mounted to the first lateral panel and the second lateral panel. The spring assembly is pivotably mounted to the cam. The spring assembly is configured to bias the cam toward the bolt.
