The shelf support is used to support the right side of the shelf in the freezer section of your refrigerator. If the shelf support breaks it can cause the shelf to be uneven and the shelf support will need to be replaced. The support is white in color, measures approximately 1 1/2”, and is made of plastic. This is the right side support only. Left support is not included, must be ordered separately. This is a genuine OEM part and is sold individually.
