Abstract
A hinge including a device bracket, a door bracket, a first arm, a second arm, and a closure device is provided. The first arm mounts to the device bracket at a first pin and to the door bracket at a second pin. The second arm mounts to the device bracket at a third pin and to the door bracket at a fourth pin. The third pin is closer to an axis of rotation of a door than the first pin when the door is in a closed position. The closure device includes a closure device body mounted to move with the second arm, a rod mounted within the closure device body, a spring, a spring retainer mounted to the rod, and a nut mounting the rod to the device bracket. The spring is mounted between the spring retainer and the closure device body to exert a force on the second arm.
