Abstract
A locking system for an enclosure, including a control bracket mounted to a door of the enclosure and configured to slide in a longitudinal direction along a guide rod running through a pin bracket of the control bracket. The control bracket further includes a latching pin to secure the door of the enclosure. A handle mechanism has a push rod that causes the control bracket to slide along the longitudinal direction, also causing the latching pin to move into a position that secures the door.
