Abstract
A door close assembly for a merchandiser including a case defining a product display area and having a case frame. The refrigerated merchandiser further includes a door pivotably coupled to the case frame and enclosing at least a portion of the product display area. The door close assembly includes a door close mechanism configured to be positioned between the case frame and the door to permit movement of the door between a closed position and an open position, and the door close mechanism has a base plate attached to the case frame and a spiral spring supported by the base plate. The spiral spring responds to a closing force of the door to maintain a substantially constant door close force.
