ABSTRACT:
A door assembly for a chute system comprising a door pivotally connected to a frame assembly mountable around an opening in a chute system. The door is manufactured from stainless steel and is free of welds. The door includes an automatic closer mounted to its interior surface and being directly connected to the frame assembly at one end and to the door at the other end. When the door is opened, the closer moves with the door out of the opening to the chute system, thereby increasing the usable space for inserting articles into the chute. The closer does not intrude into the interior of the chute when the door is in a closed position. The door may also include a deflector plate mounted proximate the door hinge to protect the hinge and prevent debris from articles inserted into the chute from dropping into the gap between the door and frame and interfering with the action of the hinge.
