ABSTRACT:
The present invention relates to electrical enclosures having a cabinet and a door connected by hinges and in particular to a hinge which allows a door, while closed, to be flush with a surface that surrounds the perimeter of the cabinet door opening. The hinge system utilizes a spring that pushes the door in a direction that is generally normal to and away from the cabinet, creating a space between the peripheral flange on the door and the surface that surrounds the cabinet door opening thus allowing the door to swing freely as it is opened and closed. The door can be held closed by use of various latching systems. While the door is in the closed position, latches near the hinges will compress the hinge springs, eliminating the space between the door and the cabinet opening.
