Abstract
Abstract A mounting frame for a refrigerator door is disclosed, having a channel-shaped mullion with a front wall and a pair of side walls. Two angle-shaped insulating cover strips are mounted on the mullion. Each cover strip has a side leg covering one of the side walls thereof, and a front leg covering the adjacent portion of the front wall. A lip is provided on each side wall to retain the corresponding side leg. The front wall is formed with a pair of lips to retain the front legs. A cover plate, made of magnetic stainless steel or the like, is secured to the front wall so as to cover the front legs. The cover plate serves as an armature for a magnetic gasket on the door.
